Header Authorization: Bearer YOUR_API_KEYKeep keys server side.
Never ship a key in browser or mobile code: anyone who can read it can spend your allowance. Call the API from your backend, and revoke and replace a key in the dashboard if it leaks.
A missing or invalid key returns 401 unauthorized. See Errors.
