City Bikes vs TourneyRadar

City Bikes (CityBik.es) aggregates real-time bike-share data for 700+ networks worldwide into one JSON API, covering station locations, available bikes and e-bikes, free docks, and GBFS feed links where a network publishes one. It's free and keyless -- the only condition is crediting the CityBikes project and linking back to it from any app built on the data.

TourneyRadar aggregates upcoming over-the-board chess tournaments -- currently spanning 46 countries' worth of national-federation listings -- with venue, arbiter, time-control, and FIDE-rating category details pulled from federation calendars. The API is free, keyless, and returns JSON with open CORS across tournament, country, and full-text search endpoints, though optional fields like entry fees and prize pools are frequently left null by the underlying source data.
