OpenF1 vs OpenLigaDB

OpenF1 is an open-source F1 data API spanning 18 endpoints -- car telemetry at up to 3.7Hz, lap and sector times, race-control flags, pit stops, team radio, and championship standings -- returned as JSON or, by appending a query flag, CSV. Historical data back to the 2023 season is free with no API key, credit card, or signup at all; a paid Sponsor tier (about €9.90/month) only adds access during live sessions, roughly 3 seconds after real-world events. A live request confirmed the public endpoint responds keyless and echoes permissive CORS headers, matching its "zero friction" pitch.

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`.
