MLB Records and Stats vs OpenLigaDB

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.

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`.
