# Errors

> HTTP response codes used by the Bondio API

Bondio uses conventional HTTP response codes to indicate the success or failure of an API request. In general: codes in the `2xx` range indicate success. Codes in the `4xx` range indicate an error that failed given the information provided (e.g., a required parameter was omitted). Codes in the `5xx` range indicate an error with Bondio's servers (these are rare).

| HTTP Code    | Type                 | 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 was provided.                                                                             |
| `403`        | Forbidden            | The API key doesn't have permissions to perform the request.                                               |
| `404`        | Not Found            | The requested resource doesn't exist.                                                                      |
| `412`        | Preconditions Failed | The request couldn't be processed, often due to an invalid parameter value or preconditions not being met. |
| `429`        | Too Many Requests    | Too many requests hit the API too quickly. We recommend an exponential backoff of your requests.           |
| `500`, `502` | Server Errors        | Something went wrong on Bondio's end.                                                                      |
