When it fails

  • SymptomBuilt-in Cursor models stop working while the override is enabled
    Codeclient-side

    Cursor's OpenAI base-URL override is global. Turn it off when switching back to models served by Cursor rather than MiniRouter.

  • SymptomThe override works, but requests still pass through Cursor
    Codeclient-side

    Cursor builds the final request on its own backend before forwarding it to the overridden endpoint. This is not a direct client-to-MiniRouter connection.

  • Symptom404, HTML, or a parse error on every request
    Codeinvalid_request

    Almost always the base URL. Use https://api.minirouter.sh/v1 — the bare host without /v1 also works, but never append /chat/completions to the base URL field; the client adds that path itself. docs/errors#invalid_request →

  • Symptom401 on every request
    Codeinvalid_api_key

    Wrong or rotated key. Keys start with mr-live-; after a rotation the old key keeps working for 24 hours, then dies. docs/errors#invalid_api_key →

Every API error string carries a URL resolving to /docs/errors.
