ChatGPT Plus OAuth succeeds but third-party Codex calls return 429 quota exceeded

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

Important notes:

• This is not an OAuth login failure
• This is not a local OpenClaw gateway failure
• This is not a non-Plus account case
• Issue appears specific to third-party OAuth Codex usage through OpenClaw

Questions:

1. Is ChatGPT Plus OAuth expected to provide usable quota for third-party Codex/OpenClaw calls?
2. Does third-party OAuth Codex usage use a different quota/billing context from first-party usage?
3. Are additional credits required even when Plus is active?

Thank you for clarifying whether this is expected behavior, an account-side quota routing issue, or a known product limitation.

To Reproduce

Minimal reproduction:

1. Run: openclaw models auth login --provider openai-codex
2. Run: openclaw models set openai-codex/gpt-5.4
3. Run: openclaw agent --agent main --message hi --thinking off --json

Observed result: Request reaches openai-codex/gpt-5.4 but returns 429 quota error.

Additional context: This issue has been successfully reported via the OpenAI Python library GitHub repository. The problem occurs when using ChatGPT Plus OAuth authentication with third-party tools (OpenClaw) - authentication succeeds but actual API calls return 429 quota errors despite having an active Plus subscription.

Next steps: Waiting for OpenAI team response (typically 1-3 business days). Will update this issue with any additional logs or information requested.

Status: Issue tracking initiated for OpenAI OAuth quota routing problem.

The chatGPT Plus OAuth succeeds but third-party Codex calls return 429 quota exceeded issue seems straightforward enough. I'll work through it and push a fix.

This is frustrating for Plus users. The OAuth flow works but quota is exceeded for third-party calls - there might be a bug in how quota is tracked across different API endpoints. Thanks for investigating!
