Odds data
Lines and prices are read from the public FanDuel Sportsbook and FanDuel daily fantasy pages and normalised into one schema. FanDuel API is an independent data service operated by FF API Inc.

Player photos, rosters and box scores
Player headshots, rosters, injury reports and final box scores come from ESPN's public sports data. Headshots are linked from ESPN's image servers (a.espncdn.com) rather than copied, and each headshot_url in the API points there. Box scores are used to grade props. ESPN is a trademark of its owner; FanDuel API is not affiliated with or endorsed by ESPN.
A player gets a headshot and a grade only when they match exactly one ESPN athlete on the right team; see graded examples.
