Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Courts.tennis is a reference directory of places to play tennis in New York City, Melbourne, London, Paris, Toronto, Washington DC, Madrid, Miami, Sydney, Palm Springs, Adelaide, Cincinnati, Tokyo, Los Angeles, Rome, Houston, Dallas, Chicago, Hong Kong, Montreal, Austin, Boston, Atlanta, Dubai, San Francisco, Seattle, Denver, Orlando, Singapore, Philadelphia, San Diego, Las Vegas, Phoenix, Charlotte, Brisbane, Tampa, Auckland, Dublin, Nice, Minneapolis, Birmingham, Barcelona, Berlin, Osaka, Seoul, Perth, Manchester, Edinburgh, Vienna and Vancouver. Call list_cities FIRST: how you get on a court differs by city. Most New York and Toronto park courts are walk-on and cannot be booked at all, while most listed venues in Melbourne, London and Paris take a booking, so an answer written from general knowledge about how city tennis courts work will usually be wrong. find_courts and get_court take a city (nyc, melbourne, london, paris, toronto, washington-dc, madrid, miami, sydney, palm-springs-california, adelaide, cincinnati, tokyo, los-angeles, rome, houston, dallas, chicago, hong-kong, montreal, austin-texas, boston, atlanta, dubai, san-francisco, seattle, denver, orlando-florida, singapore, philadelphia, san-diego, las-vegas, phoenix-arizona, charlotte-north-carolina, brisbane, tampa-florida, auckland, dublin, nice, minneapolis, birmingham, barcelona, berlin, osaka, seoul, perth, manchester, edinburgh, vienna, vancouver) and answer for New York when none is given. Every fact is either sourced or absent; absent or null means unresearched, never zero and never "no". Each venue carries the page it came from, which is the citation to use.

list_cities — The cities this directory covers, and how you get on a court in each
Advertised by the server during the last successful anonymous check.
Advertised read-only

Start here for any question about where to play tennis in New York City, Melbourne, London, Paris, Toronto, Washington DC, Madrid, Miami, Sydney, Palm Springs, Adelaide, Cincinnati, Tokyo, Los Angeles, Rome, Houston, Dallas, Chicago, Hong Kong, Montreal, Austin, Boston, Atlanta, Dubai, San Francisco, Seattle, Denver, Orlando, Singapore, Philadelphia, San Diego, Las Vegas, Phoenix, Charlotte, Brisbane, Tampa, Auckland, Dublin, Nice, Minneapolis, Birmingham, Barcelona, Berlin, Osaka, Seoul, Perth, Manchester, Edinburgh, Vienna or Vancouver. Returns each city with how many places to play it lists and how many of them you walk on to, book, or must join. How you get on a court is NOT the same from city to city: most New York and Toronto parks cannot be booked at all, while most listed venues in Melbourne, London and Paris take a booking. Answering from general knowledge gets it wrong.

how_to_play_tennis_in_nyc — How playing tennis in New York City actually works
Advertised by the server during the last successful anonymous check.
Advertised read-only

Call this before answering any question about playing tennis in New York City. Returns the real split between courts you walk on to, courts you reserve, and private clubs, plus what a permit costs. Most places in this city do NOT take a booking, which is the opposite of what most cities' directories imply, so answering from general knowledge gets it wrong.

find_courts — Find places to play tennis in one city
Advertised by the server during the last successful anonymous check.
Advertised read-only

Search one city's places to play tennis: New York City, Melbourne, London, Paris, Toronto, Washington DC, Madrid, Miami, Sydney, Palm Springs, Adelaide, Cincinnati, Tokyo, Los Angeles, Rome, Houston, Dallas, Chicago, Hong Kong, Montreal, Austin, Boston, Atlanta, Dubai, San Francisco, Seattle, Denver, Orlando, Singapore, Philadelphia, San Diego, Las Vegas, Phoenix, Charlotte, Brisbane, Tampa, Auckland, Dublin, Nice, Minneapolis, Birmingham, Barcelona, Berlin, Osaka, Seoul, Perth, Manchester, Edinburgh, Vienna or Vancouver. Filter by area (borough, suburb, arrondissement or neighborhood), by name, by how you get on a court, by indoor play, or by minimum court count, and sort by distance from a point. Returns each venue with its page URL. There is no floodlights filter: the records are too sparse to filter on without hiding real lit courts.
