City Bikes vs RacingHub

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.

RacingHub is a Formula 1 statistics API spanning every season from 1950 to the present, exposing per-driver career records (wins, poles, podiums, points), race results, and analytical features like racecraft heatmaps and pit-stop strategy breakdowns, with official Python and JavaScript client libraries and an MCP server for querying the data conversationally. No API key is required -- a live keyless request to the real `racinghub.net/api/v1/drivers/...` backend returned genuine per-driver data (200) with a wildcard `Access-Control-Allow-Origin` header, resolving `cors: unknown -> yes`, though anonymous requests are rate-limited to 100/minute per the response headers.
