OpenLigaDB vs TourneyRadar

OpenLigaDB is a free, community-maintained JSON API for German football and other league results -- Bundesliga, 2. Bundesliga, and dozens of amateur/regional competitions -- with matches, tables, and goal-getters contributed and corrected by its own user community rather than an official league feed. No registration or API key is required to read from it, only for submitting corrections. A live probe of the real `api.openligadb.de` host reconfirmed keyless access and a wildcard `Access-Control-Allow-Origin`.

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.
