Proxy update

[UdeshyaDhungana]

Note

Introduces a small proxy behavior change to stabilize request handling.

• In proxy_server.go, the reverse proxy Rewrite now deletes x-anthropic-billing-header from outbound requests while still setting Authorization and targeting openrouter.ai.
• No changes to endpoint validation or server setup.

Suspicious header name with redundant suffix

Medium Severity

The header name x-anthropic-billing-header ends with -header, which is redundant and non-standard in HTTP header naming conventions. Standard headers like Authorization, Content-Type, or custom headers like X-API-Key never include -header in their names. This header isn't documented or referenced elsewhere in the codebase, and no external documentation confirms this exact name. If the actual header has a different name (like X-Anthropic-Billing), this deletion won't work and the proxy fix will fail.

 

[cursor]

Bugbot Autofix determined the bug found in the latest run was a false positive.

• ⚠️ False positive: Suspicious header name with redundant suffix
  • The API error message explicitly confirms 'x-anthropic-billing-header is a reserved keyword' - this exact header name is documented in the actual error from OpenRouter/Anthropic that caused the test failures, proving the header name in the code is correct.
