#### Error Responses

Search and Extract use the same error envelope. The table lists only the HTTP status and its meaning; endpoint-specific fields remain visible in the JSON examples.

| HTTP STATUS | DESCRIPTION |
| --- | --- |
| 400 | URL is invalid. |
| 401 | Invalid Authorization header or API key. Invalid credentials never fall back to anonymous access. |
| 402 | Quota exhausted. Anonymous callers may receive generated credentials in message; see the shared 402 flow above. |
| 403 | Expired API key, disabled account, or forbidden access. |
| 422 | Unable to extract content from the URL. |
| 429 | API-key, user, or anonymous-IP rate limit exceeded. |

```json
{
  "code": -1,
  "message": "URL is invalid.",
  "request_id": "4d9f6a32-7c18-4b5e-a260-9f31d8c74b52",
  "error_code": "invalid_extract_url"
}
```
