Authentication

Learn how to authenticate with the API using X-API-Key header

Authentication is performed via HTTP header authentication. Provide your API key as the X-API-Key header value. All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.

Example

X-API-Key: $API_KEY

Replace $API_KEY with your actual API key.
