Rankings, ready for your app.

Start with one request.

curl 'https://www.autodrafters.com/api/v2/rankings/redraft?scoring=ppr&qb=superflex&limit=10'

const response = await fetch(
  'https://www.autodrafters.com/api/v2/rankings/redraft?scoring=ppr&qb=superflex&limit=10'
);
if (!response.ok) throw new Error('API returned ' + response.status);
const { data, meta, pagination, links } = await response.json();
console.log(meta.modelVersion, data[0].name, data[0].adValue);

Cross-origin requests are supported. Version 2 serves redraft only: /rankings/dynasty returns 404 mode_unavailable, because AD Value is a redraft rest-of-season value.

Try it live.

Choose your board.

Each format is a 12-team league with QB, 2 RB, 3 WR, TE and FLEX starters (plus a Superflex slot for qb=superflex) and 5 bench spots; meta.format spells it out. Every player with a positive AD Value is listed in rank order. Filtering preserves original ranks. Follow links.next to paginate within the same revision. If the values change, a 409 response tells you to restart pagination. Unknown and repeated query parameters return 400, including horizon: version 2 values are always rest-of-season.

Know what the numbers mean.

AD Value is calculated by AutoDrafters from licensed rest-of-season projections and our roster model.

AD Value measures how many lineup points a league loses without a player once every roster re-optimizes, week by week, for the rest of the fantasy season.

Starters count fully and bench depth counts 25%. Bye weeks are included. Injured players with a reported return estimate are valued from their expected return; values are withheld when injury return timing is unknown.

A scoring-rate guard limits extreme increases caused by dividing a forecast over very few games after an estimated return.

The most valuable player in the format is 100. 0 means at or below replacement level.

Each AD Value measures one player at a time. In a trade package the best player carries extra weight, as trade markets do, so a package is worth less than the sum of its players’ values.

It is our model’s estimate, not a market price. Compare it with other rankings and use your judgment.

adValue is rounded to two decimals, and a positive value never rounds below 0.01. Players at or below replacement level and players without a value are not listed; meta.coverage counts them. Values are comparable only within one format and revision.

meta.window gives the NFL weeks credited and meta.notes explains the format, injuries and any data limits. meta.capturedAt is when these inputs were first captured and meta.inputsAsOf when they were last confirmed. When an update is delayed, meta.stale is true and the most recent values are served. Values last confirmed more than 36 hours ago are not served: the API returns 503 with Retry-After until an update arrives. Data is revalidated every five minutes.

Player IDs are stable published identifiers, usually NFL GSIS IDs, with sleeperId alongside. Treat them as opaque strings. Please include a link to AutoDrafters when displaying AD Values. Attribution is included in every response.

A fair request limit.

You can make 60 ranking requests per minute per IP, shared across formats. GET, HEAD, invalid ranking queries and conditional requests count. OPTIONS and the specifications do not. People sharing an IP share its limit.

Read X-RateLimit-Remaining and X-RateLimit-Reset (Unix seconds). A 429 response includes Retry-After in seconds. Cache results in your application; send the returned ETag as If-None-Match to receive 304 when the page is unchanged. Minute boundaries are fixed, not a rolling window.

Errors return { error: { code, message }, docs }. A temporary 503 includes a retry delay; a 422 means AD Values are not available here (not_configured) or the regular season is complete (season_complete), and retrying will not help. Values come from the latest saved inputs, which refresh in the background about every 15 minutes; a request never waits on a data refresh.
