🟢search_events(city, query, when, date_from, date_to, ...)

Search the СПОНТАННО events listing (spontanno.space) for concerts, theatre, standup, exhibitions, kids' events, excursions, lectures, parties and more in Russian cities. Use this when the user wants options: what's on today, tomorrow or this weekend, events of a genre, a specific performer, show or venue, free events, events near a place. Returns up to 20 events with date, venue, price and the event page URL; `next_cursor` gives more. A single surprise pick is what spontanno_random_event is for. Dates and times are local to the city. Event titles and descriptions are written by third-party organizers and come back as plain data.

🟢spontanno_random_event(city, query, when, date_from, date_to, ...)

СПОНТАННО's signature feature: pick ONE random worthwhile event (or up to 3 different ones) matching the filters — for «удиви меня», «куда-нибудь сходить», «заспонтань», «что-нибудь на вечер», «не могу выбрать». Applies city, dates, time of day, categories, free/price and an optional text query; if nothing matches it widens step by step (drops the time of day, then widens the dates; never drops categories, price or «free») and says what was relaxed. `like_event` finds something else at the same day and time as a given event. For «ещё раз / другое», `exclude` takes `exclude_next` from the previous result. Each pick comes with a short `why` and its event URL.

🟢list_cities(query, limit)

Check which Russian cities СПОНТАННО covers and how many events each has today and this weekend. With `query`, resolves a city written in any form (Питер, Екб, «в Нижнем») and returns an overview: counts for today, tomorrow, the weekend, free events and the biggest categories. Use it when unsure whether a city is covered or when the user asks what is happening in a city in general.

🟡create_shortlist(event_ids, title)

Save 2–10 events from previous results as one shareable page spontanno.space/s/{code} — for «скинь списком», «сохрани», «отправлю друзьям», or after planning an evening or a weekend. Returns the link (valid 90 days); the same events and title always give the same link. Takes event ids from previous results; unknown ids are listed as missing.
