Dining demand research

Compare public restaurant availability snapshots

Research public restaurant discovery and the availability currently displayed by Resy and OpenTable. Produce a dated snapshot and a shortlist; these surfaces do not create, hold, modify, or cancel reservations, purchase event tickets, or guarantee a table remains available.

Resolve the restaurant and request context

1. Establish the requested place, party size, local dining date/time, and any cuisine, price, or accessibility preferences. Resolve ambiguous venues by provider ID first, then name plus street address/neighborhood; never mix a Resy restaurant_id with an OpenTable restaurant_id.
2. For Resy, discover a city with GET /resy/locations (q, country), then use returned location codes/IDs for GET /resy/cuisines (location) and GET /resy/events (location, optional date, limit, offset). Search venues with GET /resy/search (latitude, longitude, optional term, date, party_size, size); date adds current slots to the results.
3. For OpenTable, use GET /opentable/search with required term, latitude, and longitude, plus optional date_time, party_size, and size. Use a returned ID with GET /opentable/restaurant (restaurant_id, optional date_time, party_size) to refresh that venue's profile and slots.
4. Fetch provider-specific detail when it improves the decision: GET /resy/restaurant or GET /resy/availability (restaurant_id, date, optional party_size); GET /opentable/restaurant/menus or GET /opentable/restaurant/reviews (restaurant_id, optional page, size). Menu and review data support discovery; they do not prove a table is available.

Time, availability, and pricing

• Resy dates are YYYY-MM-DD; OpenTable date_time is RFC3339-minute local format. Normalize the requested moment to the restaurant's verified local time zone before the call, retain the original local date/time and zone in the output, and do not label an offset-free local time as UTC.
• Capture retrieved_at immediately for every availability call, alongside source, provider ID, requested date/time, party size, and canonical URL when returned. Treat returned slots as an observed snapshot: they can change between calls and do not hold inventory.
• Party size defaults to 2 on availability/search/detail calls when omitted. Request the user's actual party size; a result for one party size cannot be generalized to another. Search result limits default to 10 for Resy and OpenTable; Resy's event list also defaults to 10, while OpenTable reviews default to page 1 with 20 reviews. Do not imply undocumented maximums.
• A venue price tier/band is an affordability signal, not a menu total. Use actual menu prices only where returned, preserve currency and scope, and do not infer taxes, fees, deposits, minimums, or reservation cost.

Keep regular reservations distinct from events

Resy GET /resy/events lists ticketed, fixed-price/fixed-capacity dining events, not ordinary reservation slots. For one event, call GET /resy/event with the event result's event_url_slug, restaurant_url_slug, and the same location (optional party_size) to inspect ticket packages and their live availability. Report event availability, tier price, inclusions, and event-day instructions separately from restaurant reservation availability. This is read-only research, never a ticket purchase.

Deliverable and bounds

Return a comparison with venue name, provider and provider ID, verified address/neighborhood, cuisine, price signal, requested local date/time/zone, party size, observed slots or explicit lack of slots, source URL, and retrieved_at. State which facts are discovery/profile data versus a time-specific availability snapshot. Compare only like-for-like party sizes and local times; a missing slot is not proof of a sellout, closure, or lack of demand. Keep sources separate unless venue identity is independently verified.
