    find_gymsFind Brazilian jiu-jitsu and grappling gyms by city, by country, or near a point. Give at least one of: city, country, or lat+lng. Returns at most 25 gyms per call (no pagination: narrow the area for more specific results). Each gym has a link to its public page on bjjsquare.com, where contacts and full details are shown. Use get_gym with the slug for the class schedule and what the gym offers.
    get_gymPublic details of one gym by its slug (from find_gyms): address, website, affiliation, what it offers, class schedule when the gym has published one, and when the schedule was last updated. Only known facts are returned: a missing field means unknown, not "no". Phone and email are on the gym page linked in the result.
    list_placesCountries covered by BJJ Square with gym counts, or, with a country code, the cities of that country with gym counts (largest 200). Use it to check coverage before find_gyms.
