Best free sports data API
An honest roundup of genuinely free sports data APIs for stats, scores, and betting odds, including non-ParlayAPI options.
It depends on the data you need. For stats and scores, MLB's Stats API, balldontlie for NBA, and the nflverse open data project are genuinely free. For betting odds, ParlayAPI's free tier includes 1,000 credits per month and the-odds-api's includes 500. For soccer fixtures, football-data.org offers a free tier.
More detail
For league stats and scores, the free options are genuinely good. MLB's Stats API is deep and publicly accessible. balldontlie covers NBA players, games, and stats with a generous free tier. The nflverse project publishes open NFL play-by-play and roster data files that power most public NFL analytics. football-data.org offers free soccer fixtures and results for major competitions, and TheSportsDB provides free multi-sport metadata like teams and schedules.
Betting odds are different: books do not publish free firehoses, so odds providers meter free access. ParlayAPI's free tier is 1,000 credits per month with no credit card, covering live odds, props, and a 48 hour historical window; the-odds-api offers 500 credits free. Both are real free tiers, not trials.
The practical pattern for a model or product is to combine them: free stats sources for player and team data, plus an odds API free tier for prices, upgrading only the odds side when volume demands it.

FAQ
Is there a free API for live betting odds?
Free tiers rather than unlimited free products: ParlayAPI includes 1,000 credits per month and the-odds-api includes 500. Live-game streaming feeds are paid features at every serious provider.
What is the best free NFL data source?
The nflverse open data project for play-by-play, rosters, and historical stats. Pair it with an odds API free tier when your analysis needs prices as well as stats.
Why is odds data never fully free?
Odds must be collected continuously from books that do not give it away, so providers meter access to fund collection. Stats and scores flow from leagues and public records, which is why those APIs can be free.
