Eat App Concierge Availability API

  title: Eat App Platform API
  description: >-
    Eat App is a restaurant reservation and table management platform. This
    document models its two documented, partner/key-gated REST surfaces plus a
    small honestly-modeled table-management surface:

    1. Partner API (base /partners/v2) - for booking channels to read
    availability and post reservations.

    2. Concierge API (base /concierge/v2) - for restaurants, vendors, and groups
    to sync reservations, guests, availability, and reference data (resources,
    groups, restaurants). Requests are scoped with X-Group-ID and X-Restaurant-ID
    headers and can be created idempotently via an idempotency_token.

    3. Tables and Floor Plans (base /concierge/v2) - MODELED. No public tables or
    floorplan endpoints are documented; these operations are honestly modeled on
    Eat App's documented resource conventions and should be confirmed with a
    partner API key before use.

    All responses follow a JSON:API-style structure (data objects carrying id,
    type, and attributes). Every request is authenticated with a Bearer token
    (the API key Eat App issues to a partner or Concierge user). The sandbox host
    is https://api.eat-sandbox.co and production is https://api.eatapp.co.
    Endpoints are rate limited to roughly 60 requests per minute.
