  description: 'Flynet''s partner API. Read access to member context, restaurants,

    locations, check-ins, and memberships; write access for payment

    intents.


    **Base URL:** staging `https://api.staging.blackbird.xyz/flynet/v1`.


    **Auth:** Two schemes — OAuth bearer (`Authorization: Bearer ...`) for

    member-scoped routes, API key (`X-API-Key`) for restaurant and

    location discovery. See Concepts → Authentication.


    **Pagination:** `page` is zero-indexed (default `0`); `page_size`

    default `50`. List responses include a `pagination` wrapper except

    `GET /locations/{id}/open_hours`.


    **Errors:** see Concepts → Pagination + errors. Three envelope shapes

    are documented there.
