Codex OAuth

Authenticate with OpenAI Codex, refresh tokens automatically, and stream responses through the CORS proxy.

Connection Status
Send a Codex Message
Use the Codex responses endpoint with streaming output.
Usage & rate limits
Reads the ChatGPT backend usage endpoint at /backend-api/wham/usage using your Codex OAuth token.

A 401 means the token is expired — re-authenticate in Settings and try again.

No usage data yet. Click refresh to load your current plan and rate limits.

How this works
  1. Start Codex OAuth from Settings to authorize with OpenAI.
  2. Paste the callback URL here to exchange the code for tokens and store them locally.
  3. Requests are sent through the CORS proxy with your access token and account ID.
  4. Streaming responses are parsed client-side and rendered above.
