Additional Information

I can’t use it for the last 2 weeks

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey @Gunasekaran_C

In this case, the BYOK model you’ve selected doesn’t support tool use. This means it isn’t going to be usable in Cursor, which relies heavily on tools to perform its work.

{
  "error": {
    "type": "provider",
    "reason": "provider_error",
    "message": "Provider returned 404",
    "retryable": false,
    "provider": {
      "status": 404,
      "body": {
        "error": {
          "message": "No endpoints found that support tool use. Try disabling \"Shell\". To learn more about provider routing, visit: https://openrouter.ai/docs/guides/routing/provider-selection",
          "code": 404
        }
      }
    }
  }
}

You’ll probably need to select a different model.
