Resy F

Best for Diners booking in person through the app.

Verdicts

Eat App Partner API

A diner-side Partner API with idempotent booking, a stated rate limit, per-API status monitoring and a changelog updated on 13 October 2026, plus a read-only MCP server for restaurants. Partnerships are activated restaurant by restaurant, API access is priced through sales, and the docs are a Postman collection without OpenAPI or llms.txt.

Resy

Resy is a large diner reservation network, now including Tock's venues, with American Express behind it. There is no public API or MCP server an outside agent can call today. An Amex-hosted MCP endpoint exists but accepts only pre-registered clients and has no public documentation, and Resy's own terms and privacy pages could not be read.

Before you call either

Eat App Partner API

  1. Send a unique idempotency_token with each new booking so a retry returns the first result
  2. Use POST /partners/v2/availability/range, not the legacy availability endpoint
  3. Keep include_tables ranges to 24 hours or less and pass covers with it
  4. Stay under 60 requests a minute and wait for the next minute after a 429
  5. Cancel by PATCH with status canceled, after which the reservation can no longer change

Resy

  1. Don't plan to call Resy from another agent. Hand the booking to the person in the Resy app, or use a client that American Express has approved for its dining MCP
  2. Do not automate the Resy website or app, since Resy runs a bot-detection programme against automated booking
