# API Error Codes

> Infercom API error codes and HTTP status codes. Common error types, causes, and how to resolve them.

The Infercom API uses standard HTTP response status codes to indicate whether an API request was successful or failed.

When a request fails, the API responds with a JSON object containing details about the error. These include:

* **Error code**
  * Identifies the type of error.
* **Parameter** (if applicable)
  * Specifies the property causing the error.
* **Error message**
  * Provides a clear explanation of the issue.

## Error message

This error message indicates that a parameter value exceeded the allowed maximum. The `top_p` parameter received a value of `100`, whereas it should be between `0` and `1`. The error type is `invalid_request_error`, with the code `decimal_above_max_value`.

```python Example error message theme={null}
{
  "error": {
    "message": "Decimal above maximum value. Expected a value between 0 and 1, but got 100 instead.",
    "type": "invalid_request_error",
    "param": "top_p",
    "code": "decimal_above_max_value"
  }
}
```

## Error categories

Use the following table to understand the various error categories.

| HTTP status | Category             | Description                                                                    | Suggestion                                       |
| :---------- | :------------------- | :----------------------------------------------------------------------------- | :----------------------------------------------- |
| 400         | Bad request          | The server couldn't process the request due to invalid syntax or input values. | Review the API request syntax and parameters.    |
| 401         | Unauthorized         | Authentication credentials are missing or invalid.                             | Ensure valid API key/token is included.          |
| 408         | Request timeout      | The server terminated the request due to excessive processing time.            | Retry the request with optimized payload.        |
| 410         | Gone                 | The requested model is no longer available (deprecated or removed).            | Use a currently supported model.                 |
| 429         | Too many requests    | Rate limit exceeded for your subscription tier.                                | Implement rate limiting or upgrade tier.         |
| 429         | Queue Full           | Too many requests are currently in flight; the server declined the request.    | Retry after a short delay or reduce concurrency. |
| 500         | Something went wrong | A server-side error occurred.                                                  | Retry later or contact support if persistent.    |
| 503         | Maintenance          | The model is temporarily unavailable due to maintenance.                       | Try again after some time.                       |

<Tip>
  If you are experiencing 500 or 503 errors, check the [Infercom Status Page](https://status.infercom.ai) for any ongoing incidents or scheduled maintenance before contacting support.

## Error code reference

Use the following table to understand and troubleshoot errors programmatically.

| HTTP status | Error code                | Description                                                         | Suggestion                                                                                                                       |

| 400         | `context_length_exceeded` | Input/output tokens exceed model context limits.                    | Reduce prompt and response length to stay within model limits.                                                                   |
|             | `invalid_type`            | Parameter type mismatch (e.g., expected int but got float).         | Check the expected parameter types and correct the input.                                                                        |
