Sleeper
READY
Stats & awards Draft assistant All-time history League scoring
Public read-only API, no account or key needed. Read-only by design.
ESPN Fantasy
READY
Stats & awards Draft assistant All-time history League scoring
Undocumented but publicly readable API. Public leagues work with no credentials; private ones need two cookies from a logged-in session.
Needs: Private leagues need espn_s2 and SWID cookies
Yahoo Fantasy
NEEDS SETUP
Stats & awards Draft assistant All-time history League scoring
The only officially documented API of the four, and read-only like Sleeper. Fantasy Sports is no longer self-serve: Yahoo reviews each request. Our adapter's team, week and draft parsers are not written yet — Yahoo returns a positional JSON structure that needs its own normaliser, which cannot be built without approved access to see real responses.
Needs: An OAuth2 app from developer.yahoo.com, plus separate approval for Fantasy Sports data at sports.yahoo.com/developer/access
Waiting on: OAuth credentials, Fantasy Sports approval, then our parsers
NFL Fantasy
MOVED TO ESPN
Stats & awards Draft assistant All-time history League scoring
NFL Fantasy was retired in 2026 — ESPN is now the Official Fantasy Game of the NFL. Existing leagues migrate to ESPN with their settings and history intact, and connect here through ESPN, which supports every feature.
Connect via ESPN → Migrate your league first
These badges are measured, not marketing. A platform is only marked ready if its API actually exposes what the feature needs — awards depend on per-player bench scoring, which not every platform publishes.
