# Errors

Decentri uses standard HTTP response codes to communicate the outcome of API requests. Codes in the 2xx range signify a successful operation. Codes in the 4xx range indicate an error due to invalid input or missing information, such as an omitted parameter or a failed transaction. Codes in the 5xx range represent server-side errors within Decentri.

### Status Codes

| Status Code        | Status Message    | Description                                                                        |
| ------------------ | ----------------- | ---------------------------------------------------------------------------------- |
| 200                | OK                | Everything worked as expected.                                                     |
| 400                | Bad Request       | The request was unacceptable, often due to missing a required parameter.           |
| 401                | Unauthorized      | No valid API key provided.                                                         |
| 402                | Request Failed    | The parameters were valid but the request failed.                                  |
| 403                | Forbidden         | The API key doesn’t have permission to perform the request.                        |

| 409                | Conflict          | The request conflicts with another request (e.g., using the same idempotent key).  |
| 429                | Too Many Requests | Too many requests were made to the API in a short period. Use exponential backoff. |
| 500, 502, 503, 504 | Server Errors     | Something went wrong on Decentri’s end.                                            |
