title: "Errors"
---
Gravv uses conventional HTTP response codes to indicate whether an API request succeeds or fails. Codes in the **2xx** range indicate success. Codes in the **4xx** range indicate an error caused by the information provided. Codes in the 5xx range indicate a server error and occur rarely.

Some **4xx** errors can be handled programmatically. Each error includes a code and a message that explains the issue.

## Status code summary

| Status code | Error                 | Description                                                                                            |
| :---------- | :-------------------- | :----------------------------------------------------------------------------------------------------- |
| 200         | OK                    | Everything worked as expected.                                                                         |
| 400         | Bad request           | The request was unacceptable because it missed a required parameter.                                   |
| 401         | Unauthorized          | You either did not provide your `Api-key` (`Secret Key`), or the `Api-key` you provided was incorrect. |
| 404         | Not found             | The requested resource doesn’t exist. One possible reason is an incorrect URL path.                    |
| 429         | Too many requests     | You hit the rate limit. Slow down and retry after a short pause. See [Rate limits](/getting-started/rate-limits). |
| 500         | Internal server error | An error occurred on Gravv's servers. These errors are rare and resolve automatically.                 |
