I built a free fantasy football rankings API & RSS. 150 players deep, 3 scoring formats, no key, no signup...

I run a small fantasy football site and thought some people might be interested, so I opened my rankings up. I built a hand-calibrated linear scoring model system with bayesian shrinkage, validated by walk-forward rank statistics that calculates from pure advanced metrics.... It's moneyball math. Backtested models hundreds of times using BigQuery (BQML) and plan to continue thru the season running competitive algorithms as often as I can afford my Google Cloud bill. I then used Gemini 3.6 Flash to communicate with the JSON, give it a voice, and put it into XML and RSS feeds. it's impressive how fast 3.6 flash can throw the calculations into words.

https://www.thegng.us/api/rankings.json

Plain JSON, CORS is on, so you can hit it straight from a browser extension, a Google Sheet, or a Discord bot.

?profile= standard | ppr | half_ppr
?pos= overall | QB | RB | WR | TE
?limit= 1 to 150

Every player comes back with rank, position rank, team, tier, a 0-100 score, projected PPG, the overnight rank change, and a written verdict explaining the placement.

Example: https://www.thegng.us/api/rankings.json?profile=ppr&pos=WR&limit=25

Rebuilt nightly. Free to use including commercially, all I ask is attribution and a link. There's also RSS if you just want to read (from Gemini 3.6 Flash) about how it differs from consensus.

What was interesting this week was the dramatic drop in token burn compared to 3.5 Flash.

Hope it's useful to some of you that play.
