RacingHub vs TourneyRadar

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.

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.
