Thank you for reporting this issue.

Analysis:

The error "This endpoint only accepts requests from Claude Code CLI" is returned by your upstream CRS (Claude Relay Service), not by claude-code-hub itself. This happens when the upstream service detects that the request is not coming from an official Claude Code CLI client.

This is the same issue that was reported in #200. According to the resolution discussion there:

1. For "Test Provider" button in Dashboard: claude-code-hub does send the official User-Agent header (claude-cli/2.0.50 (external, cli)) when testing providers. However, some relay services may detect non-CLI clients through request body content inspection (e.g., checking for metadata fields, message structure, etc.), not just User-Agent headers.

2. For actual Claude Code CLI requests: When you use the real Claude Code CLI through claude-code-hub, the client's original User-Agent is transparently forwarded to the upstream provider via src/app/v1/_lib/headers.ts. The HeaderProcessor.process() method preserves the User-Agent header (it's not in the blacklist).

Relevant code:

• src/app/v1/_lib/proxy/forwarder.ts (lines 1886-1986) - Header building for upstream requests
• src/app/v1/_lib/headers.ts (lines 95-117) - Header processing logic (User-Agent is preserved)
• src/lib/provider-testing/utils/test-prompts.ts (lines 22-29) - User-Agent strings used for provider testing

To help diagnose this, please provide:

• Are you seeing this error when using the "Test Provider" button in the Dashboard, or when making actual requests from Claude Code CLI?
• Is your upstream provider a CRS relay service (like the one mentioned in 测试供应商claude报错 #200)?
• Can you share the trace-level logs (LOG_LEVEL=trace) when the error occurs?

Important note:
The Dashboard's "Test Provider" function is designed for basic connectivity checks. As noted in #200, some relay services perform deeper client verification that the test function cannot satisfy. If actual Claude Code CLI requests work correctly through claude-code-hub, the test result can be considered informational only.

并不是重复的问题，这个问题不是在测试时候产生的，而是真实使用cli调用时候的日志错误

好像只是在请求haiku时候有问题，opus可以正常请求。

您好，请问是否可以提供本地 claude code 版本。
按道理新版客户端已经不会请求 claude 3.5 版本模型。
