DiscGolf vs TourneyRadar

DiscGolfAPI catalogs disc golf courses worldwide with location, hole counts, and a confidence score showing how well each listing has been verified, aimed at map and directory builders rather than official tour data. The public read endpoints (courses, countries, regions) need no API key and return JSON, throttled only by a fair-use policy against excessive automated traffic; a separate POST endpoint lets anyone submit corrections.

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.
