    ## Authentication


    All API endpoints (except Auth and Health) require one of:

    - `X-Api-Key: sk_live_xxx` header (recommended for server-side)

    - `Authorization: Bearer sk_live_xxx` header

    - `?access_key=sk_live_xxx` query parameter (for GET endpoints)


    Dashboard endpoints use JWT Bearer tokens obtained from `/auth/login`.
