From public data checked . How we know
Choose MyFantasyLeague API if you…
Fantasy platform
- ✓ want to start on a free tier
- ✓ need commercial use allowed in the public terms
- ✓ value a large open-source ecosystem of wrappers and examples
What developers say
Fantasy football platform API with read and write JSON or XML exports, used by hobbyists and dynasty-league tools for trades, start percentages and draft data; several community wrappers exist, and ffscrapr supports it. Discussion is mostly old and thin, with little about reliability, limits or pricing, so overall opinion is unclear.
Choose Yahoo Fantasy Sports API if you…
Fantasy platform
Best for: Apps that read or manage a user's Yahoo fantasy football, baseball, basketball or hockey leagues, rosters and matchups through OAuth.
- ✓ need Baseball, Basketball, Ice hockey
- ✓ care most about what developers report in practice
Not ideal for: General sports stats, scores or odds; the API exposes Yahoo fantasy data only, scoped to leagues the authorising user belongs to.
What developers say
Used by hobbyists to pull their own fantasy league data for dashboards, bots and analytics, with community wrappers in Node, Go and Python. Developers struggle with OAuth setup, XML-only responses, thin docs and missing fields such as projections or stats. Access is limited to approved apps and rate-limited.
