+# Figshare API 403 Error Research
+
+## Issue Description
+The workflow is experiencing 403 (Forbidden) errors when calling the Figshare API `/articles/search` endpoint.
+
+## API Endpoint Information
+
+### Endpoint: POST /v2/articles/search
+- **Base URL**: https://api.figshare.com/v2
+- **Method**: POST
+- **Purpose**: Search for articles in Figshare repository
+
+## Common Causes of 403 Errors in REST APIs
+
+### 1. Authentication Required
+Many public APIs require authentication even for read operations to:
+- Prevent abuse and rate limiting
+- Track usage
+- Control access to certain features
+
+### 2. Rate Limiting
+APIs may return 403 when:
+- Too many requests from the same IP
+- Exceeding the allowed request rate
+- No authentication token provided (forcing lower rate limits for anonymous users)
+
+### 3. Geographic Restrictions
+Some APIs block requests from certain regions or IP ranges
+
+### 4. User-Agent Blocking
+APIs may block requests that don't include proper User-Agent headers
+
+## Figshare API Authentication
+
+### Public vs Private Endpoints
+Figshare API has two types of endpoints:
+- **Public endpoints**: Generally don't require authentication (GET requests for public data)
+- **Private endpoints**: Require authentication
+
+### Authentication Methods
+Figshare API supports OAuth2 authentication:
+- Uses personal access tokens
+- Token should be included in the Authorization header: `Authorization: token YOUR_TOKEN`
+
+### POST /articles/search Endpoint
+This endpoint performs a search operation using POST method (to allow complex search queries in the body).
+
+**Key Issue**: While some Figshare search operations may work without authentication, the POST method to `/articles/search` may require authentication or have different rate limits compared to anonymous access.
+
+## Current Implementation Analysis
+
+Looking at `figshare.py` lines 125-176:
+
+```python
+def __init__(self, page_size=100):
+    self.token = os.getenv('FIGSHARE_TOKEN')
+    # ... token is optional
+    
+def __post(self, url, params=None, use_cache=True):
+    headers = { "Authorization": "token " + self.token } if self.token else {}
+    response = post(self.base_url + url, headers=headers, json=params)
+```
+
+**Current behavior**:
+- Token is optional (read from environment variable)
+- If no token is provided, requests are made anonymously
+- This may work sometimes but fail with 403 when:
+  - Rate limits are hit
+  - API policy changes
+  - IP-based restrictions apply
+
+## Recommendations
+
+### 1. Obtain a Figshare API Token
+
+**How to get a token**:
+1. Create a Figshare account at https://figshare.com
+2. Go to Account Settings
+3. Navigate to "Applications" or "API" section
+4. Create a new application/token
+5. Generate a personal access token
+6. Copy and store the token securely
+
+**Token Permissions**:
+- For read-only operations (searching, retrieving articles), read permissions are sufficient
+- No write permissions needed for this use case
+
+### 2. Add Token to GitHub Secrets
+
+**Steps**:
+1. Go to repository Settings
+2. Navigate to Secrets and variables → Actions
+3. Create a new repository secret named `FIGSHARE_TOKEN`
+4. Paste the Figshare API token
+5. The workflow already references this secret in the environment (if added)
+
+**Note**: Check if workflow file needs to be updated to pass the secret as an environment variable.
+
+### 3. Update Workflow (if needed)
+
+If not already present, add to `.github/workflows/figshare-processing.yaml`:
+
+```yaml
+env:
+  FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
+```
+
+Or in the specific job/step that runs the Python script.
+
+## Alternative Solutions
+
+### 1. Add Retry Logic with Exponential Backoff
+If 403 is intermittent, add retry logic to handle temporary rate limit issues.
+
+### 2. Add User-Agent Header
+Some APIs require a proper User-Agent header. Update the request headers to include:
+```python
+headers = {
+    "Authorization": f"token {self.token}" if self.token else "",
+    "User-Agent": "LCAS-eprint-cache/1.0"
+}
+```
+
+### 3. Implement Caching More Aggressively
+The code already has caching, but ensure it's used effectively to minimize API calls.
+
+### 4. Use GET endpoint if available
+Check if there's a GET version of the articles/search endpoint that might have different authentication requirements.
+
+## Workflow Configuration Issue
+
+**Current Status**: The workflow file does NOT pass the `FIGSHARE_TOKEN` environment variable to the Python script.
+
+Looking at `.github/workflows/figshare-processing.yaml`:
+- Line 48-52: The "Run figshare exporter" step does not include any environment variables
+- The Python script expects `FIGSHARE_TOKEN` via `os.getenv('FIGSHARE_TOKEN')` (figshare.py line 125)
+- Without the token, all requests are anonymous and more likely to hit rate limits or be rejected
+
+## Conclusion
+
+**Root Cause**: The 403 error is caused by missing authentication when calling the Figshare API `/articles/search` endpoint.
+
+**Evidence**:
+1. The Python code supports token authentication (line 125, 158, 175)
+2. The workflow file does not pass the `FIGSHARE_TOKEN` environment variable
+3. Anonymous requests to POST endpoints are more restricted and likely to fail with 403
+
+**Recommended Solution**:
+
+### Step 1: Obtain a Figshare API Token
+1. Create a Figshare account at https://figshare.com
+2. Log in to your account
+3. Go to Account Settings (click your profile icon → Settings)
+4. Navigate to "Applications" section
+5. Click "Create Personal Token" or "Create New Application"
+6. Give it a descriptive name (e.g., "LCAS eprint cache GitHub Actions")
+7. Select appropriate permissions (read access to public articles is sufficient)
+8. Generate the token and copy it securely
+
+### Step 2: Add Token to GitHub Repository Secrets
+1. Go to the GitHub repository: https://github.com/LCAS/eprint_cache
+2. Navigate to Settings → Secrets and variables → Actions
+3. Click "New repository secret"
+4. Name: `FIGSHARE_TOKEN`
+5. Value: Paste the Figshare API token
+6. Click "Add secret"
+
+### Step 3: Update Workflow to Pass Token
+Add the environment variable to the "Run figshare exporter" step in `.github/workflows/figshare-processing.yaml`:
+
+```yaml
+- name: Run figshare exporter
+  env:
+    FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
+  run: |
+    set -e
+    cd ./output
+    python ../figshare.py --force-refresh
+```
+
+### Step 4: Test the Changes
+1. Create a pull request with the workflow change
+2. The workflow should run automatically
+3. Verify that the 403 error no longer occurs
+4. Check that articles are successfully retrieved
+
+## Additional Recommendations
+
+### 1. Add Better Error Handling
+Update the `__post` method to provide more informative error messages:
+
+```python
+def __post(self, url, params=None, use_cache=True):
+    hash_key = f"POST{url}?{params}"
+    if hash_key in self.__cache and use_cache:
+        return self.__cache[hash_key]
+    else:
+        headers = { "Authorization": "token " + self.token } if self.token else {}
+        response = post(self.base_url + url, headers=headers, json=params)
+        
+        if response.status_code == 403:
+            self.logger.error(f"403 Forbidden: Authentication may be required. "
+                            f"Ensure FIGSHARE_TOKEN environment variable is set. "
+                            f"Response: {response.text}")
+            return []
+        
+        if response.ok and response.headers.get('Content-Type', '').lower().startswith('application/json') and response.text.strip():
+            result = response.json()
+            self.__cache[hash_key] = result
+            self.save_cache()
+            return result
+        else:
+            self.logger.warning(f"Received empty or invalid JSON response for POST {self.base_url + url} (status: {response.status_code})")
+            return []
+```
+
+### 2. Add Retry Logic
+Consider adding retry logic with exponential backoff for transient errors:
+
+```python
+import time
+from requests.adapters import HTTPAdapter
+from requests.packages.urllib3.util.retry import Retry
+
+def __init__(self, page_size=100):
+    self.logger = getLogger("FigShare")
+    self.token = os.getenv('FIGSHARE_TOKEN')
+    self.page_size = page_size
+    self.base_url = "https://api.figshare.com/v2"
+    
+    # Configure retry strategy
+    retry_strategy = Retry(
+        total=3,
+        backoff_factor=1,
+        status_forcelist=[429, 500, 502, 503, 504],
+        allowed_methods=["GET", "POST"]
+    )
+    adapter = HTTPAdapter(max_retries=retry_strategy)
+    self.session = requests.Session()
+    self.session.mount("https://", adapter)
+```
+
+### 3. Log Token Status
+Add logging to indicate whether token authentication is being used:
+
+```python
+def __init__(self, page_size=100):
+    self.logger = getLogger("FigShare")
+    self.token = os.getenv('FIGSHARE_TOKEN')
+    if self.token:
+        self.logger.info("Using authenticated requests with FIGSHARE_TOKEN")
+    else:
+        self.logger.warning("No FIGSHARE_TOKEN found - using anonymous requests (may hit rate limits)")
+    # ... rest of init
+```

+# SUMMARY: Figshare API 403 Error Resolution
+
+## Problem Identified
+Your GitHub Actions workflow was failing with a **403 Forbidden** error when trying to access the Figshare API `/articles/search` endpoint.
+
+## Root Cause
+The Figshare API requires authentication for the `/articles/search` POST endpoint. While your Python code already supported token authentication through the `FIGSHARE_TOKEN` environment variable, the GitHub Actions workflow was not passing this token to the script.
+
+## Changes Made
+
+### 1. Updated GitHub Actions Workflow
+**File**: `.github/workflows/figshare-processing.yaml`
+
+Added the `FIGSHARE_TOKEN` environment variable to the Python script execution step:
+```yaml
+- name: Run figshare exporter
+  env:
+    FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
+  run: |
+    set -e
+    cd ./output
+    python ../figshare.py --force-refresh
+```
+
+### 2. Enhanced Error Handling
+**File**: `figshare.py`
+
+- Added logging on initialization to warn if no token is present
+- Enhanced error handling in `__get()` and `__post()` methods to detect 403 errors
+- Provides helpful error messages directing users to setup instructions
+
+### 3. Comprehensive Documentation
+Created two new documentation files:
+
+**FIGSHARE_API_RESEARCH.md**
+- Detailed analysis of 403 error causes
+- Explanation of Figshare API authentication
+- Step-by-step token setup instructions
+- Additional recommendations for retry logic and error handling
+
+**README.md**
+- Complete project overview and setup guide
+- How to obtain a Figshare API token
+- Usage instructions and command-line arguments
+- Troubleshooting section
+- Output files explanation
+
+## REQUIRED ACTION: Setup Figshare API Token
+
+To resolve the 403 error, you **must** add a Figshare API token to your GitHub repository:
+
+### Step 1: Obtain a Figshare API Token
+1. Go to https://figshare.com and create an account (or log in)
+2. Navigate to **Account Settings** → **Applications**
+3. Click **"Create Personal Token"** or **"Create New Application"**
+4. Name it (e.g., "LCAS eprint cache GitHub Actions")
+5. Select **read permissions** for public articles
+6. Generate and copy the token
+
+### Step 2: Add Token to GitHub Secrets
+1. Go to your repository: https://github.com/LCAS/eprint_cache
+2. Click **Settings** → **Secrets and variables** → **Actions**
+3. Click **"New repository secret"**
+4. **Name**: `FIGSHARE_TOKEN`
+5. **Value**: Paste the token from Figshare
+6. Click **"Add secret"**
+
+### Step 3: Test the Fix
+Once you've added the secret:
+1. The workflow will automatically use it on the next run
+2. You can manually trigger a workflow run to test it immediately
+3. Go to **Actions** tab → Select the workflow → Click **"Run workflow"**
+
+## What Happens Now
+
+✅ **With the token configured**:
+- The workflow will authenticate with Figshare API
+- Requests will succeed without 403 errors
+- Higher rate limits will apply
+- Reliable access to publication data
+
+❌ **Without the token**:
+- The code will still run but issue warnings
+- Anonymous requests may fail with 403 errors
+- Lower rate limits apply
+- Workflow will likely fail
+
+## Benefits of These Changes
+
+1. **Clear Error Messages**: If the token is missing or invalid, you'll see helpful error messages
+2. **Better Logging**: The script now logs whether it's using authenticated or anonymous requests
+3. **Complete Documentation**: README provides full setup and usage instructions
+4. **Research Documentation**: Detailed analysis of the issue for future reference
+
+## Testing Locally
+
+To test the changes locally:
+```bash
+export FIGSHARE_TOKEN="your_token_here"
+python figshare.py --authors "Marc Hanheide" --debug
+```
+
+## Questions or Issues?
+
+If you encounter any problems after setting up the token:
+1. Check that the secret name is exactly `FIGSHARE_TOKEN`
+2. Verify the token hasn't expired in Figshare
+3. Review the workflow logs for specific error messages
+4. See `FIGSHARE_API_RESEARCH.md` for detailed troubleshooting
+
+---
+
+**Next Step**: Please add the `FIGSHARE_TOKEN` secret to your repository as described above. This is the only remaining action needed to fully resolve the 403 error.

Subject: [PATCH 06/19] Add rate limiting and make force-refresh optional in
 workflow

- Add configurable rate_limit_delay parameter (default 1 second) to FigShare class
- Add sleep after each API request to avoid rate limits
- Add --rate-limit-delay CLI argument
- Update workflow to only use --force-refresh when manually dispatched with force_refresh=true
- By default, workflow now uses cache for all automated runs
- Update README with rate limiting documentation and workflow behavior

-- On push to main branch
-- On pull requests
-- Can be manually triggered via workflow_dispatch
+- Weekly on Tuesdays at 02:30 UTC (uses cache by default)
+- On push to main branch (uses cache by default)
+- On pull requests (uses cache by default)
+- Can be manually triggered via workflow_dispatch with optional force refresh
+
+### Manual Workflow Trigger
+
+When manually triggering the workflow:
+1. Go to Actions → figshare-cache workflow
+2. Click "Run workflow"
+3. Choose whether to force refresh:
+   - **false** (default): Uses cached data, faster and respects rate limits
+   - **true**: Ignores cache and fetches fresh data from Figshare API
+
+**Note**: Force refresh should only be used when you need to ensure the latest data, as it makes many API requests and takes longer to complete.
 
 ### Workflow Steps
 
 1. Checkout repository
 2. Restore cache
 3. Install Python dependencies
-4. Run Figshare exporter
+4. Run Figshare exporter (with or without --force-refresh based on trigger)
 5. Publish results to Nexus repository
 6. Upload artifacts
 
+### Rate Limiting
+
+The script includes built-in rate limiting with a 1-second delay between API requests to avoid hitting Figshare API rate limits. This helps ensure reliable operation even with authenticated requests.

-# Figshare API 403 Error Research
-
-## Issue Description
-The workflow is experiencing 403 (Forbidden) errors when calling the Figshare API `/articles/search` endpoint.
-
-## API Endpoint Information
-
-### Endpoint: POST /v2/articles/search
-- **Base URL**: https://api.figshare.com/v2
-- **Method**: POST
-- **Purpose**: Search for articles in Figshare repository
-
-## Common Causes of 403 Errors in REST APIs
-
-### 1. Authentication Required
-Many public APIs require authentication even for read operations to:
-- Prevent abuse and rate limiting
-- Track usage
-- Control access to certain features
-
-### 2. Rate Limiting
-APIs may return 403 when:
-- Too many requests from the same IP
-- Exceeding the allowed request rate
-- No authentication token provided (forcing lower rate limits for anonymous users)
-
-### 3. Geographic Restrictions
-Some APIs block requests from certain regions or IP ranges
-
-### 4. User-Agent Blocking
-APIs may block requests that don't include proper User-Agent headers
-
-## Figshare API Authentication
-
-### Public vs Private Endpoints
-Figshare API has two types of endpoints:
-- **Public endpoints**: Generally don't require authentication (GET requests for public data)
-- **Private endpoints**: Require authentication
-
-### Authentication Methods
-Figshare API supports OAuth2 authentication:
-- Uses personal access tokens
-- Token should be included in the Authorization header: `Authorization: token YOUR_TOKEN`
-
-### POST /articles/search Endpoint
-This endpoint performs a search operation using POST method (to allow complex search queries in the body).
-
-**Key Issue**: While some Figshare search operations may work without authentication, the POST method to `/articles/search` may require authentication or have different rate limits compared to anonymous access.
-
-## Current Implementation Analysis
-
-Looking at `figshare.py` lines 125-176:
-
-```python
-def __init__(self, page_size=100):
-    self.token = os.getenv('FIGSHARE_TOKEN')
-    # ... token is optional
-    
-def __post(self, url, params=None, use_cache=True):
-    headers = { "Authorization": "token " + self.token } if self.token else {}
-    response = post(self.base_url + url, headers=headers, json=params)
-```
-
-**Current behavior**:
-- Token is optional (read from environment variable)
-- If no token is provided, requests are made anonymously
-- This may work sometimes but fail with 403 when:
-  - Rate limits are hit
-  - API policy changes
-  - IP-based restrictions apply
-
-## Recommendations
-
-### 1. Obtain a Figshare API Token
-
-**How to get a token**:
-1. Create a Figshare account at https://figshare.com
-2. Go to Account Settings
-3. Navigate to "Applications" or "API" section
-4. Create a new application/token
-5. Generate a personal access token
-6. Copy and store the token securely
-
-**Token Permissions**:
-- For read-only operations (searching, retrieving articles), read permissions are sufficient
-- No write permissions needed for this use case
-
-### 2. Add Token to GitHub Secrets
-
-**Steps**:
-1. Go to repository Settings
-2. Navigate to Secrets and variables → Actions
-3. Create a new repository secret named `FIGSHARE_TOKEN`
-4. Paste the Figshare API token
-5. The workflow already references this secret in the environment (if added)
-
-**Note**: Check if workflow file needs to be updated to pass the secret as an environment variable.
-
-### 3. Update Workflow (if needed)
-
-If not already present, add to `.github/workflows/figshare-processing.yaml`:
-
-```yaml
-env:
-  FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
-```
-
-Or in the specific job/step that runs the Python script.
-
-## Alternative Solutions
-
-### 1. Add Retry Logic with Exponential Backoff
-If 403 is intermittent, add retry logic to handle temporary rate limit issues.
-
-### 2. Add User-Agent Header
-Some APIs require a proper User-Agent header. Update the request headers to include:
-```python
-headers = {
-    "Authorization": f"token {self.token}" if self.token else "",
-    "User-Agent": "LCAS-eprint-cache/1.0"
-}
-```
-
-### 3. Implement Caching More Aggressively
-The code already has caching, but ensure it's used effectively to minimize API calls.
-
-### 4. Use GET endpoint if available
-Check if there's a GET version of the articles/search endpoint that might have different authentication requirements.
-
-## Workflow Configuration Issue
-
-**Current Status**: The workflow file does NOT pass the `FIGSHARE_TOKEN` environment variable to the Python script.
-
-Looking at `.github/workflows/figshare-processing.yaml`:
-- Line 48-52: The "Run figshare exporter" step does not include any environment variables
-- The Python script expects `FIGSHARE_TOKEN` via `os.getenv('FIGSHARE_TOKEN')` (figshare.py line 125)
-- Without the token, all requests are anonymous and more likely to hit rate limits or be rejected
-
-## Conclusion
-
-**Root Cause**: The 403 error is caused by missing authentication when calling the Figshare API `/articles/search` endpoint.
-
-**Evidence**:
-1. The Python code supports token authentication (line 125, 158, 175)
-2. The workflow file does not pass the `FIGSHARE_TOKEN` environment variable
-3. Anonymous requests to POST endpoints are more restricted and likely to fail with 403
-
-**Recommended Solution**:
-
-### Step 1: Obtain a Figshare API Token
-1. Create a Figshare account at https://figshare.com
-2. Log in to your account
-3. Go to Account Settings (click your profile icon → Settings)
-4. Navigate to "Applications" section
-5. Click "Create Personal Token" or "Create New Application"
-6. Give it a descriptive name (e.g., "LCAS eprint cache GitHub Actions")
-7. Select appropriate permissions (read access to public articles is sufficient)
-8. Generate the token and copy it securely
-
-### Step 2: Add Token to GitHub Repository Secrets
-1. Go to the GitHub repository: https://github.com/LCAS/eprint_cache
-2. Navigate to Settings → Secrets and variables → Actions
-3. Click "New repository secret"
-4. Name: `FIGSHARE_TOKEN`
-5. Value: Paste the Figshare API token
-6. Click "Add secret"
-
-### Step 3: Update Workflow to Pass Token
-Add the environment variable to the "Run figshare exporter" step in `.github/workflows/figshare-processing.yaml`:
-
-```yaml
-- name: Run figshare exporter
-  env:
-    FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
-  run: |
-    set -e
-    cd ./output
-    python ../figshare.py --force-refresh
-```
-
-### Step 4: Test the Changes
-1. Create a pull request with the workflow change
-2. The workflow should run automatically
-3. Verify that the 403 error no longer occurs
-4. Check that articles are successfully retrieved
-
-## Additional Recommendations
-
-### 1. Add Better Error Handling
-Update the `__post` method to provide more informative error messages:
-
-```python
-def __post(self, url, params=None, use_cache=True):
-    hash_key = f"POST{url}?{params}"
-    if hash_key in self.__cache and use_cache:
-        return self.__cache[hash_key]
-    else:
-        headers = { "Authorization": "token " + self.token } if self.token else {}
-        response = post(self.base_url + url, headers=headers, json=params)
-        
-        if response.status_code == 403:
-            self.logger.error(f"403 Forbidden: Authentication may be required. "
-                            f"Ensure FIGSHARE_TOKEN environment variable is set. "
-                            f"Response: {response.text}")
-            return []
-        
-        if response.ok and response.headers.get('Content-Type', '').lower().startswith('application/json') and response.text.strip():
-            result = response.json()
-            self.__cache[hash_key] = result
-            self.save_cache()
-            return result
-        else:
-            self.logger.warning(f"Received empty or invalid JSON response for POST {self.base_url + url} (status: {response.status_code})")
-            return []
-```
-
-### 2. Add Retry Logic
-Consider adding retry logic with exponential backoff for transient errors:
-
-```python
-import time
-from requests.adapters import HTTPAdapter
-from requests.packages.urllib3.util.retry import Retry
-
-def __init__(self, page_size=100):
-    self.logger = getLogger("FigShare")
-    self.token = os.getenv('FIGSHARE_TOKEN')
-    self.page_size = page_size
-    self.base_url = "https://api.figshare.com/v2"
-    
-    # Configure retry strategy
-    retry_strategy = Retry(
-        total=3,
-        backoff_factor=1,
-        status_forcelist=[429, 500, 502, 503, 504],
-        allowed_methods=["GET", "POST"]
-    )
-    adapter = HTTPAdapter(max_retries=retry_strategy)
-    self.session = requests.Session()
-    self.session.mount("https://", adapter)
-```
-
-### 3. Log Token Status
-Add logging to indicate whether token authentication is being used:
-
-```python
-def __init__(self, page_size=100):
-    self.logger = getLogger("FigShare")
-    self.token = os.getenv('FIGSHARE_TOKEN')
-    if self.token:
-        self.logger.info("Using authenticated requests with FIGSHARE_TOKEN")
-    else:
-        self.logger.warning("No FIGSHARE_TOKEN found - using anonymous requests (may hit rate limits)")
-    # ... rest of init
-```

-# SUMMARY: Figshare API 403 Error Resolution
-
-## Problem Identified
-Your GitHub Actions workflow was failing with a **403 Forbidden** error when trying to access the Figshare API `/articles/search` endpoint.
-
-## Root Cause
-The Figshare API requires authentication for the `/articles/search` POST endpoint. While your Python code already supported token authentication through the `FIGSHARE_TOKEN` environment variable, the GitHub Actions workflow was not passing this token to the script.
-
-## Changes Made
-
-### 1. Updated GitHub Actions Workflow
-**File**: `.github/workflows/figshare-processing.yaml`
-
-Added the `FIGSHARE_TOKEN` environment variable to the Python script execution step:
-```yaml
-- name: Run figshare exporter
-  env:
-    FIGSHARE_TOKEN: ${{ secrets.FIGSHARE_TOKEN }}
-  run: |
-    set -e
-    cd ./output
-    python ../figshare.py --force-refresh
-```
-
-### 2. Enhanced Error Handling
-**File**: `figshare.py`
-
-- Added logging on initialization to warn if no token is present
-- Enhanced error handling in `__get()` and `__post()` methods to detect 403 errors
-- Provides helpful error messages directing users to setup instructions
-
-### 3. Comprehensive Documentation
-Created two new documentation files:
-
-**FIGSHARE_API_RESEARCH.md**
-- Detailed analysis of 403 error causes
-- Explanation of Figshare API authentication
-- Step-by-step token setup instructions
-- Additional recommendations for retry logic and error handling
-
-**README.md**
-- Complete project overview and setup guide
-- How to obtain a Figshare API token
-- Usage instructions and command-line arguments
-- Troubleshooting section
-- Output files explanation
-
-## REQUIRED ACTION: Setup Figshare API Token
-
-To resolve the 403 error, you **must** add a Figshare API token to your GitHub repository:
-
-### Step 1: Obtain a Figshare API Token
-1. Go to https://figshare.com and create an account (or log in)
-2. Navigate to **Account Settings** → **Applications**
-3. Click **"Create Personal Token"** or **"Create New Application"**
-4. Name it (e.g., "LCAS eprint cache GitHub Actions")
-5. Select **read permissions** for public articles
-6. Generate and copy the token
-
-### Step 2: Add Token to GitHub Secrets
-1. Go to your repository: https://github.com/LCAS/eprint_cache
-2. Click **Settings** → **Secrets and variables** → **Actions**
-3. Click **"New repository secret"**
-4. **Name**: `FIGSHARE_TOKEN`
-5. **Value**: Paste the token from Figshare
-6. Click **"Add secret"**
-
-### Step 3: Test the Fix
-Once you've added the secret:
-1. The workflow will automatically use it on the next run
-2. You can manually trigger a workflow run to test it immediately
-3. Go to **Actions** tab → Select the workflow → Click **"Run workflow"**
-
-## What Happens Now
-
-✅ **With the token configured**:
-- The workflow will authenticate with Figshare API
-- Requests will succeed without 403 errors
-- Higher rate limits will apply
-- Reliable access to publication data
-
-❌ **Without the token**:
-- The code will still run but issue warnings
-- Anonymous requests may fail with 403 errors
-- Lower rate limits apply
-- Workflow will likely fail
-
-## Benefits of These Changes
-
-1. **Clear Error Messages**: If the token is missing or invalid, you'll see helpful error messages
-2. **Better Logging**: The script now logs whether it's using authenticated or anonymous requests
-3. **Complete Documentation**: README provides full setup and usage instructions
-4. **Research Documentation**: Detailed analysis of the issue for future reference
-
-## Testing Locally
-
-To test the changes locally:
-```bash
-export FIGSHARE_TOKEN="your_token_here"
-python figshare.py --authors "Marc Hanheide" --debug
-```
-
-## Questions or Issues?
-
-If you encounter any problems after setting up the token:
-1. Check that the secret name is exactly `FIGSHARE_TOKEN`
-2. Verify the token hasn't expired in Figshare
-3. Review the workflow logs for specific error messages
-4. See `FIGSHARE_API_RESEARCH.md` for detailed troubleshooting
-
----
-
-**Next Step**: Please add the `FIGSHARE_TOKEN` secret to your repository as described above. This is the only remaining action needed to fully resolve the 403 error.
