Errors and retries

When a request fails, start with the HTTP status code and error.message in the response.

{
"error": {
"message": "Model not found",
"type": "invalid_request_error",
"code": "model_not_found"
}
}
Status Common cause What to do
400 Invalid JSON, a missing field, or an unsupported parameter Change the request according to the error message.
401 Missing or invalid API key Copy the key again and check the request header.
402 Insufficient balance Add credit or use a key with balance.
403 The key is disabled or has a model restriction Check the key’s status and restrictions.
404 Incorrect API address or model name Check the URL and copy the model name from the Pricing page again.
408 The request timed out Retry once after waiting.
413 The upload is too large Reduce the file or request size.
429 Too many requests Wait a few seconds before retrying.
5xx A temporary Omrouter or model service problem Wait and retry a small number of times.

408, 429, and 5xx errors are usually safe to retry. Wait about one second before the first retry, increase the wait after each failure, and limit the total number of attempts.

Do not retry automatically when:

  • The API key, model name, or request parameters are wrong.
  • Part of a streaming response has already been shown.
  • An image, video, or other billable task has already been created.
  1. Check that the API address points to Omrouter.
  2. Copy the API key again and check for extra spaces.
  3. Copy the model name again from the Pricing page.
  4. Remove optional features such as tools and streaming, then send the smallest possible request.
  5. Find the request at the same time in Usage logs.

If an API key appears in logs, a screenshot, Git history, or an agent conversation, delete it on the Keys page and create a new key immediately.
