Converts a place name or address into coordinates using OpenStreetMap. Returns matching places with lat/lon, a display label and the OSM id. Provider "nominatim" (default) is best for addresses; "photon" is typo-tolerant and better for fuzzy place names.

Converts coordinates into the nearest address or place name (Nominatim).

Calculates the real-world travel distance and time between two or more places, walking, driving or cycling, on OpenStreetMap data. Waypoints are visited in the given order. Set include_steps for a turn-by-turn summary. Use route_matrix to compare many pairs, optimize_route to reorder stops.

Computes travel times and distances from every origin to every destination in one call — ideal for comparing options (e.g. 5 hotels against 3 sights). Cells are null where no route exists.

Finds the best order to visit a set of stops (traveling-salesman optimization) and returns the optimized itinerary with total distance and time. With roundtrip (default) the tour returns to the first stop; without it the first stop is the start and the last stop the end.

Shows how far you can get from a place within a time or distance budget ("what is reachable in 15 minutes on foot?"). Returns a compact summary of the reachable area: bounding box and reach per compass direction. Give exactly one of minutes or kilometers.

Finds points of interest near a location, sorted by distance. Category shortcuts: restaurant, cafe, bar, pub, fast_food, ice_cream, hotel, hostel, guest_house, apartment, camp_site, attraction, museum, gallery, viewpoint, information, artwork, castle, monument, ruins, supermarket, bakery, convenience, pharmacy, hospital, doctors, police, atm, bank, fuel, charging_station, parking, toilets, drinking_water, bus_stop, train_station, tram_stop, ferry_terminal, bicycle_rental, car_rental, playground, park, beach, swimming_pool. Any other OSM tag works as "key" or "key=value" (e.g. "diet:vegan=yes"). Use poi_details for the full record of one result.

Fetches the full OpenStreetMap record of one element — all tags (opening hours, website, phone, …), coordinates and a map link. Takes an OSM id as returned by find_nearby_pois or geocode, e.g. "node/240109189".

Suggests a fair place to meet for people starting from different locations: finds venues around the geographic midpoint and picks the one with the most balanced travel times for everyone.

Great-circle ("as the crow flies") distance between two places. Instant and independent of any road network — use route for real travel distances.

Generates openstreetmap.org links to open in a browser: a marker link for a single place, or a directions link when from and to are given. Provide either "place", or both "from" and "to".
