+# Nory x402 Payment Tools
+
+Enable CrewAI agents to make payments using the x402 HTTP protocol.
+
+## Description
+
+These tools allow AI agents to handle HTTP 402 "Payment Required" responses programmatically. When an agent encounters a paywall, it can:
+
+1. Get payment requirements (amount, networks, wallet address)
+2. Verify a signed transaction
+3. Settle the payment on-chain (~400ms)
+4. Retry the original request
+
+## Installation
+
+```bash
+pip install 'crewai[tools]'
+```
+
+## Tools
+
+| Tool | Description |
+|------|-------------|
+| `NoryPaymentRequirementsTool` | Get payment requirements for a resource |
+| `NoryVerifyPaymentTool` | Verify a signed payment before settlement |
+| `NorySettlePaymentTool` | Submit payment to blockchain (~400ms) |
+| `NoryTransactionLookupTool` | Look up transaction status |
+| `NoryHealthCheckTool` | Check service health |
+
+## Example
+
+```python
+from crewai import Agent, Task, Crew
+from crewai_tools import NoryPaymentRequirementsTool, NorySettlePaymentTool
+
+# Create tools
+payment_tools = [
+    NoryPaymentRequirementsTool(),
+    NorySettlePaymentTool(),
+]
+
+# Create an agent with payment capabilities
+payment_agent = Agent(
+    role="Payment Handler",
+    goal="Handle payment requests for premium APIs",
+    backstory="Expert at processing x402 payments",
+    tools=payment_tools,
+)
+
+# Create a task
+task = Task(
+    description="Check what payment is needed for /api/premium/data at $0.10",
+    agent=payment_agent,
+)
+
+# Run
+crew = Crew(agents=[payment_agent], tasks=[task])
+result = crew.kickoff()
+```
