Authorizations

Authorization · string · header · required

API Key authentication. For all API requests, include your API Key in the Authorization HTTP Header, prefixed with Bearer . Example: Authorization: Bearer {API_KEY}. Strongly recommend storing your API Key on the server-side, not shared or stored on the client-side, to avoid possible API-Key leakage that can lead to serious consequences. Requests with a missing or invalid API key fail with HTTP 401 and error code unauthorized.
