MLB Records and Stats vs TourneyRadar

This entry documents MLB's own `statsapi.mlb.com` backend -- the same undocumented, keyless JSON API that powers MLB.com and its official apps -- covering teams, rosters, schedules, box scores, standings, and decades of historical stats, reverse-engineered and mirrored in the community `mlb-data-api-docs` reference. There's no official support or SLA since MLB never published it as a public product, but it has stayed stable and free for years. A live probe of the real host returned data with no API key and a wildcard `Access-Control-Allow-Origin`, resolving `cors: unknown -> yes` and correcting `https: false -> true` -- the stored `false` was stale, the host is https-only.

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.
