Classic Audioguide

Identify the most likely published exhibit shown in a visitor's uploaded photo. ChatGPT provides the documented file object with a temporary download URL and file ID; the API fetches the image from the URL. Requires the group keyword and a language. Supply exhibitionId from find_exhibitions when the group has several exhibitions. The user photo is sent to the configured Gemini vision model for matching against that exhibition's live exhibit catalog. Returns a likely match, confidence, short visual explanation and alternatives; it can report an uncertain match instead of guessing. Ask the visitor before sending a photo if they did not clearly offer one for identification.

Find published exhibitions by title/keyword or around a city. Set nearMe=true only when the user requests nearby results; optional ChatGPT coarse location metadata is then used. An explicit location always takes priority. With neither location nor nearMe, search globally. Follow location_required or ambiguous_location results by asking the user. Distances are relative to an approximate city location, not the visitor's exact position.
