Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cities

list_cities

List the cities this server covers, with the site that publishes each city's events, the regions covered, how many upcoming events are listed, the earliest and latest upcoming dates, the published languages, and how fresh the data is. Call this first to discover valid city values for the other tools. This server is read-only: it takes no bookings and confirms no prices.

event

event_details

Return the full record for one event: the long description, every booking link its page carries, the stay link where present, and the page URLs in every published language. For Japan events the result also includes event_class, the site's browse-to-book class (A: tickets bookable online; B: ticketed, sold through the organiser's official channels, not on the site; C: free and unticketed, travel-worthy; D: free and unticketed, local; E: ticketing handled by the organiser, unproven either way), and availability, the availability line the event page itself carries, word for word. Events whose site does not classify them return event_class and availability as null. Ended events are returned flagged ended: true with their dates, never presented as upcoming. Look the event up by the id returned by search_events or whats_on, or by its canonical page URL. This server is read-only: it takes no bookings, and prices and availability are confirmed on the merchant's site.

events

search_events

Search verified events in one city. Results are sorted by start date and include the event page, the calendar (.ics) link, the verification date and, where the event page carries one, a booking link. Dates marked expected are expected dates, not yet confirmed by the organiser. If from_date and to_date are omitted, the window defaults to today through today plus 30 days in the city's local time. An empty result includes the nearest later date that does have events. This server is read-only: it takes no bookings, and prices and availability are confirmed on the merchant's site.

whats

whats_on

Answer the common question "what is on in this city" over a named window, using fixed definitions in the city's local time: this_weekend means Friday to Sunday; if today is Saturday or Sunday it means the current weekend, otherwise the coming one. this_week means today through the coming Sunday. next_7_days means today through today plus 6 days. today means today only. Results are sorted by start date and include the event page, the verification date and, where the event page carries one, a booking link. Dates marked expected are expected dates, not yet confirmed by the organiser. This server is read-only: it takes no bookings, and prices and availability are confirmed on the merchant's site.
