Stuck? Start here.

A page says the request failed. What does that mean?

The site could not reach the API, or the API had no artifact for what was asked (for example a week that has not been published). Nothing is substituted in place of missing data; try again later or pick a published week.

Why is a week missing from the predictions?

Only weeks the scheduled job actually published exist. If the job held a week, there is no file for it and the API returns a not-found error for that week.

Why does a player have no page?

Player pages exist only for players that appear in the champion’s held-out test rows or in a published predictions file.

Can I import my league?

No. There is no league import, account, or saved roster. The draft board and start/sit tools work entirely from the published artifacts.

Where do the numbers on the evaluation page come from?

From the evaluation artifact named at the top of that page. The same file is committed in the repository.

The API and this frontend are both in the repository. Start the API with uvicorn ffai.serve.app:app --port 7860, set NEXT_PUBLIC_API_URL for the frontend, and every page will read from your local artifacts.
