Where Our Data Comes From
Last updated: October 20, 2026
Stats Guy Fantasy is built on publicly available data that we don’t own and don’t claim to. This page lists what we read and how each source is credited.
Sleeper
Sleeper’s public API provides the league, roster, and player data behind our tools, and the completed trades our values are solved from. Sleeper’s weekly player projections (produced by RotoWire), live scores, and NFL schedule power the playoff odds. Read subject to their terms.
ESPN
ESPN’s public league API provides data for publicly viewable ESPN leagues, which powers power rankings, team analysis, and the schedule matrix. Private leagues can’t be read.
Fleaflicker
Fleaflicker’s public API provides league, roster, scoreboard, trade, and draft data for Fleaflicker leagues, which powers power rankings, team analysis, the schedule matrix, and the trade tools.
MyFantasyLeague
MyFantasyLeague’s export API provides league, roster, standings, schedule, trade, and draft data for public MFL leagues, which powers power rankings, team analysis, the schedule matrix, and the trade tools. Private leagues can’t be read.
Fantrax
Fantrax’s REST API provides league, roster, standings, matchup, and draft data, and Fantrax’s league pages provide trade history and past seasons, for public Fantrax NFL leagues. Together they power power rankings, team analysis, the schedule matrix, and the trade tools. Private leagues can’t be read.
NFL team names, logos, and related marks are the property of the National Football League and its teams.
nflverse
Injury history and availability on player pages, and the injury return timelines in playoff odds, come from nflverse-data, an open community project that publishes NFL data going back to 2009. We use their weekly injury reports and roster status designations.
nflverse-data is published under the Creative Commons Attribution 4.0 International (CC BY 4.0) license. We have modified it: weekly rows are grouped into continuous injury spells, summarized for display, and fitted into return-to-play timelines. Those derived views are ours, and nflverse does not endorse Stats Guy Fantasy or anything we’ve built from their data.
Accuracy
We aim to represent these sources faithfully, but we can’t guarantee the completeness, reliability, or availability of data we don’t control. If something looks wrong, tell us at contact@statsguyfantasy.com.
