Data restrictions
We have a few cases with data that are not freely available. This is marked in the documentation for each product, under the heading Restrictions. For more information, see License and Data Use.
Versions
See the documentation for product versioning. We also recommend reading the section about error handling.
Errors and return values
Sometimes things don't go as planned. The API will return a (hopefully)
explanatory message, formatted as HTML (if using a browser or sending an
Accept: text/html request header), otherwise as plain text.
For more information, see the HTTP status codes documentation. In addition you can also check the HTTP status code and the X-ErrorClass response header when using an automated client.
ErrorClass header
In addition to the HTTP Status Code the API also returns an X-ErrorClass response header which might explain further the cause of the error. The following codes are currently used:
| ErrorClass | Status Code | Description |
|---|---|---|
| Ratelimitation | 429 Too Many Requests | Traffic rate limitation |
| IllegalUserAgent | 403 Forbidden | Please use a unique, identifying User-Agent header |
| Validation | 404 Not Found | Validation error |
| ServiceUnavailable | 503 Service Unavailable | Server error |
| Internal | 500 Internal Server Error | Something inside me broke |
| Outsidetimerange | 404 Not Found | I have no data for the requested date/time |
| Nodata | 404 Not Found | We have no data for this request |
| Doesnotapply | 400 Bad Request | Requested operation does not apply |
| ErrorFromBackend | 502 Bad Gateway | Backend error |
| Format | 400 Bad Request | Invalid formatting |
| Parameter | 400 Bad Request | Invalid parameter |
| Unexpectedmissingdata | 502 Bad Gateway | I cannot find my data |
| Encoding | 400 Bad Request | Character set encoding error |
| Outsidegeographicarea | 422 Unprocessable Entity | The location is outside the geographic area supported by the product. |
| Permissiondenied | 401 Unauthorized | Permission denied |
| Accesscontrol | 401 Unauthorized | Access control error |
This list is non-exhaustive, additional codes can be added over time (normally implemented in future versions).
Note that Unexpectedmissingdata returned a 404 in the old (version 2) API. This was changed as it really is not a Client Error but an error in the backend, but that was impossible for the user to discern.
