The Supertone API uses an API-key authentication scheme with a custom header.
Include this header on every request. Missing or invalid keys return 401 Unauthorized; keys without permission for the resource return 403 Forbidden.

​
Issue a key

Sign in at the developer console and create a new key. You can have up to 3 active keys per account; revoke and reissue from the console at any time.
