Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 8

cancel_booking

Cancel an upcoming booking and release its slot to other guests. Identified like check_booking: booking_id plus manage_token. Confirm with the guest before calling; the cancellation is immediate and this server cannot undo it, the guest would simply book again. The venue is notified exactly as for a cancellation from the manage link. Safe to retry: cancelling a booking that is already cancelled returns the same result, not an error. A booking whose start time has passed cannot be cancelled and returns an error saying so. To move a booking to another time, cancel it and create a new one.

Discovered
check_availability

List bookable time slots for a business on a given date and party size. Offer the guest only slots where available is true.

Discovered
check_booking

Look up one existing booking so the guest can confirm when and where it is. Identify it with the booking_id and manage_token that create_booking returned; both also sit in the guest's confirmation email as the manage link, /booking/<booking_id>?token=<manage_token>. Returns the business, the local date and time with its timezone, party size, service and status: confirmed, pending_confirmation, pending_payment (with payment_url while it can be paid), cancelled, or for past bookings completed or no_show. Never returns the guest's name, email or phone. A wrong or missing token is refused without revealing whether the booking exists.

Discovered
create_booking

Create a real reservation. Use a start value returned by check_availability. Never invent guest details. Ask the person for their real name, email and phone first. If the result status is pending_confirmation, show the guest the confirmation_url. If it is pending_payment, the venue takes a prepayment: show the guest the payment_url, and do not say it is booked until it is paid.

Discovered
fetch

Fetch full details for one business id returned by search: services, hours, timezone and how to book it.

Discovered
get_business

Look up a business on G-Guest: services, opening hours, timezone and maximum party size. Call this first if you only know the slug.

Discovered
request_listing

Ask G-Guest to list a business that is not on it yet. Use it when the person you are helping runs a restaurant, cafe, bar, salon, spa, studio or clinic and wants reservations that assistants can make. Nothing is published by this call: the request reaches the G-Guest team as a lead, a person reviews it and contacts the business, and only then is anything set up. The owner's or manager's email is required, because the reply comes by email; a phone is optional extra. Do not call it for a guest who merely wants to book somewhere, and never submit a business without its owner's or manager's say-so. Returns a receipt with a reference id; no timeline is promised.

Discovered
search

Search bookable businesses on G-Guest by name or slug. Returns ids you can pass to fetch or to the booking tools.
