Data

Data and API

Everything the site shows comes from these endpoints, and they're open: no key, no sign-up. Responses are compressed JSON (or CSV and iCalendar files below), read-only, and refreshed as the model updates through the day.

JSON

Plain GET requests. Leagues are nfl, nba, mlb and nhl; ids are ESPN's, the same ones in the site's addresses.

The rules

Up to 120 requests a minute from one address, and 40 a minute for the calls marked so (they reach the live feeds). Past that you get a 429 with a Retry-After header; every response carries RateLimit-Limit and RateLimit-Remaining.
For scripts, servers and spreadsheets: browsers on other sites can't call it directly (no cross-origin access), so fetch it from your own code and cache what you need. Forecasts change at most every few minutes.
Schedules, scores, injuries and lines come from ESPN's public feeds; the forecasts and everything derived from them are ours. For insight and fun, not betting advice. How each number is made is on the track record page.
