Tools · 9
search_merchantsFilter-based search over the restaurant registry (coverage cities + timezones in get_registry_meta). NOT ranked: results come back in deterministic order (merchant_id ASC by default; distance ASC when lat/lng given and order_by="distance"). Returns compact records with paginationget_merchantEvery field the registry holds on one merchant: schema fields, structured hours, raw feedback history, platform-observed operational stats, and per-field provenance with timestamps. Maximal data, zero opinion — the registry never scores or ranks.get_availabilityV1 does NOT hold live table availability — availability is checked on the phone call at booking time. This tool returns the merchant's reservation policy, structured hours, and holiday exceptions so you can pick a plausible time before calling place_booking.place_bookingRequest a table reservation. Returns booking_id with state 'queued' immediately; fulfillment is asynchronous (a call is placed to the merchant). Poll get_booking_status or supply callback_url for webhooks. RETRY SAFETY: pass a unique client_reference_id (recommended: always); if get_booking_statusState machine position for a booking: pending → queued → in_progress → confirmed | failed | needs_input (plus cancelled). Includes structured details on confirmation (confirmed_time, confirmation_code, merchant_instructions), structured failure reason (no_answer | fully_booked | modify_bookingAmend a booking before or after the call. For a booking in needs_input: pass accept_option_index to take one of the merchant's offered times (confirms immediately), or pass a new datetime/party_size to re-queue an amended request. Modifying an already-confirmed booking cancels itcancel_bookingCancel a booking in any non-terminal state, or a confirmed reservation (the registry notifies the merchant). Cancellation is mandatory when the human no longer wants the table — no-shows destroy merchant trust and are tracked per developer key.submit_feedbackReport how a confirmed reservation actually went. Accepted only against a confirmed booking_id, once per booking, within 14 days of confirmation. Structured fields first; optional free text ≤ 500 chars. This corpus is served raw to all agents via get_merchant — it is never editorget_registry_metaEvaluate the registry itself: per-city coverage (with each city's IANA timezone), merchant/bookable counts, verification and freshness stats, feedback corpus size, schema version, and the documented deterministic ordering rule. Honest by design — including how stale the data is.Recent checks
