The /api/oauth/usage endpoint places requests without a claude-code User-Agent into an aggressively rate-limited bucket that returns HTTP 429 regardless of poll interval, and does not recover for the rest of the session. This makes the extension show "Error / HTTP 429" indefinitely. Adding a `User-Agent: claude-code/<version>` header moves requests into the normal bucket and the endpoint returns usage data as expected.

Problem
The
/api/oauth/usageendpoint places requests without aclaude-codeUser-Agent into an aggressively rate-limited bucket that returns HTTP 429 regardless of poll interval, and does not recover for the rest of the session. In this extension that surfaces as a permanentError/HTTP 429in the panel, making usage monitoring unusable.This is a known upstream issue affecting every third-party tool that polls this endpoint:
Fix
Add a
User-Agent: claude-code/<version>header to the usage request. This moves the request into the normal rate-limit bucket and the endpoint returns usage data as expected.Testing
Verified directly against the live endpoint:
Single-line behavioral change plus an explanatory comment; no other files touched.
