## Authentication

- Send `Authorization: Bearer <API_KEY>` with every request. Create a key at https://aicharged.io/admin/account/api-keys.
- OAuth 2.1 (PKCE S256) is available for clients that cannot send a static key (ChatGPT).
- Without a key the endpoint answers 401 with a WWW-Authenticate header that points to https://aicharged.io/.well-known/oauth-protected-resource.
