Definition
Requests send Authorization: Bearer <API_KEY>. A missing or invalid key returns 401 Unauthorized, and the docs treat the key as the account boundary for listing models and calling Jev.
The official SDKs read TYPESAFE_API_KEY from the environment by default, so local setup is an environment variable plus the console to create the key.
