Error Response Format

{
  "error": {
    "message": "Invalid API key provided: sk-nex-xxx...xxx.",
    "type": "authentication_error",
    "code": "invalid_api_key"
  }
}

Common Errors and Solutions

`invalid_api_key`

Invalid API key provided

Cause: The API Key is incorrect or has been deleted.

Solution: Go to the console to verify the key status and re-copy the full key.

`model_not_found`

Model 'xxx' not found

Cause: The model ID is misspelled, or the model is not enabled for your plan.

Solution: Check the model ID for correctness (model IDs are case-sensitive). Query the /v1/models endpoint to retrieve the full list of available models.

`rate_limit_exceeded`

Rate limit exceeded

Cause: Request frequency has exceeded the RPM (requests per minute) quota.

Solution: Reduce request frequency and increase the interval between requests. Contact support if you need a higher quota.

`context_length_exceeded`

This model's maximum context length is xxx tokens

Cause: The combined input and output token count exceeds the model's context limit.

Solution: Reduce the input length or lower the max_tokens parameter.

Retry Strategy

For 429 and 5xx errors, we recommend exponential backoff:
