# Stats Guy Fantasy

> Dynasty and redraft fantasy football player and pick values, derived from 1M+ real trades across Sleeper leagues. The site offers value rankings, a trade calculator, player pages with value history, and league tools for Sleeper leagues. All value data is also available through a free, open API: no API key, no authentication, open CORS, so it can be called directly from scripts, browser apps, and AI agents.

The site's rankings, trade calculator, and player pages are interactive web apps; the API serves the same underlying data in JSON and is the recommended way for programs and agents to access it. Base URL: `https://api.statsguyfantasy.com/api/v1`. The API root is a discovery endpoint that lists every endpoint and its parameters as JSON. Rate limit: 60 requests per minute per IP. Commercial use is permitted; publicly distributed products that display the data must include a visible credit linking back to Stats Guy Fantasy (terms: https://statsguyfantasy.com/terms).
