Oddsmagnet vs OpenF1

Oddsmagnet is a UK-focused odds-data provider covering football, basketball, baseball and more from 17+ bookmakers (William Hill, Betway, Unibet, and others), aimed at arbitrage comparison and machine-learning models trained on historical odds movement. The free tier only exposes odds aggregated to a daily level; paid Historical Odds Data and Betting Odds API tiers unlock full granularity and low-latency live feeds. A live probe of the real `api.oddsmagnet.com` backend confirmed it's a genuine, live AWS API Gateway service distinct from the bot-protected marketing domain, and reconfirmed a wildcard `Access-Control-Allow-Origin` on every request, keeping `cors: yes`.

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.
