It acts for the venue. Seller-level writes need Plus or Premium, services with a no-show fee can't be booked through it, and it hasn't changed since September 2024.\n\n**Tock.** Tock takes reservations and experience bookings for restaurants and wineries and now feeds its venues into Resy. There is no public API or MCP server an outside agent can call today. api.exploretock.com publishes reservation data models without endpoints, and the Terms of Use forbid automated access to the site.\n\n## Before you call either\n\n### Square Appointments (Bookings API)\n\n1. Act for the seller. This API books into one Square seller's calendar, not across businesses\n2. Call RetrieveBusinessBookingProfile and check `support_seller_level_writes` before trying to create or cancel a seller-level booking\n3. Call SearchAvailability first, then CreateBooking with the service variation ID and version, team member, location and customer\n4. Send a fresh `idempotency_key` on each create, update or cancel, and pass `booking_version` when cancelling\n5. Check `no_show_fee` on the service. A service with a non-zero fee must be booked by the customer elsewhere\n\n### Tock\n\n1. Don't plan to call Tock from another agent. Hand the booking to the person on exploretock.com or in the Resy app\n2. Do not script the Tock website, which the Terms of Use forbid. A venue wanting data should ask Tock through its dashboard account\n\n## Questions\n\n### Which is better for AI agents, Square Appointments (Bookings API) or Tock?\n\nSquare Appointments (Bookings API) scores 68.1 (B) on agent readiness against Tock's 12.4 (F), and leads in every scored category.\n\n### Can an agent call Square Appointments (Bookings API) and Tock without installing anything?\n\nSquare Appointments (Bookings API) has a hosted endpoint at https://connect.squareup.com/v2/bookings.
