Build on the board.
Mock-draft ADP, sealed pre-draft ledgers, hindsight re-grades and trade-value tables — the kind of data that usually sits behind a four-figure annual paywall, served free over JSON. No key, no signup, no delay. One condition: if you publish with it, link back to the page you pulled it from.
The deal
Everything on this page is free for any use — newsletters, Discord bots, research papers, models trained on top of ours — with one requirement: visible attribution. A link to the Draftanomics page the data came from (a ledger snapshot, a re-grade) wherever the numbers appear. “Data: Draftanomics” with a link is enough.
Every public response carries a reminder in its headers:
X-Draftanomics-Attribution: required - free with a visible link; see https://draftanomics.com/developers
If you are citing a pre-draft claim, cite the ledger. Snapshots are sealed before the draft and shipped with a content hash, so “here is what the model said in February” is verifiable — by you and by anyone checking your work.
Quick start — no key, works from a browser, a bot or a notebook:

The endpoints
Base URL: https://draftanomics.com. All endpoints return JSON. Paths not listed here — anything under auth, user state or admin — are not part of the public API and can change or disappear without notice.
- GET /api/prospects/{player_id}/consensus
One prospect's consensus detail: the aggregated rollup plus every raw per-source mention — which analyst had him where.
curl "https://draftanomics.com/api/prospects/{player_id}/consensus" - GET /api/ledger
The ledger index: every draft year with sealed pre-draft snapshots. Add /{year} for the snapshot list, /{year}/latest for the newest, or /{year}/{snapshot_id} for one frozen board with its hash.
curl "https://draftanomics.com/api/ledger/2026/latest" - GET /api/regrade/{year}
A past class re-graded against real careers: round 1 versus career value, the redraft top 32, steals, busts and consensus misses. /api/regrade/years is the index; add /{team} for one franchise. Note: the `w_av` field carries Career Score (our open-data career-value index) — the field name is retained so existing integrations keep working.
curl "https://draftanomics.com/api/regrade/2020/KC" - GET /api/years/{year}/mock-consensus
Mock-draft ADP: where the mock-draft industry has each prospect going, rolled up across outlets. Sub-routes: /sources, /disagreements (mock ADP versus board rank) and /movers (risers and fallers).
curl "https://draftanomics.com/api/years/2026/mock-consensus/movers" - GET /api/prospects/{player_id}/mock-consensus
One prospect's mock-draft view: the aggregated pick-ADP plus every raw per-source projection.
curl "https://draftanomics.com/api/prospects/{player_id}/mock-consensus" - GET /api/way-too-early
Transparent recruiting-composite boards for classes too young to have a consensus (2028 and later). Filter with ?year, ?position_group, ?limit.
curl "https://draftanomics.com/api/way-too-early?year=2028&limit=25" - GET /api/slot-baseline
What a typical pick at each draft slot actually returns: expected career-value percentile for picks 1 through 260, fit as a monotone curve on real careers. The baseline our re-grades measure against.
curl "https://draftanomics.com/api/slot-baseline" - GET /api/trade-charts/{chart}
A full pick-value table, picks 1 through 260, for one trade chart: chase_stuart, jimmy_johnson, fitzgerald, pff or rich_hill. Static — cache it hard.
curl "https://draftanomics.com/api/trade-charts/rich_hill"
Withdrawn endpoints
Research update, September 1, 2026: Draftanomics withdrew its prior career-value, tier, bust-probability, and AAV validation claims following a chronology and outcome-maturity audit. Every endpoint that served model predictions or hindsight-weighted grades — tier predictions, bust probabilities, sleeper/edge rankings, the weighted consensus board, and related surfaces — is withdrawn and returns 410 Gone rather than stale numbers. Do not describe any Draftanomics model as validated, out of sample, or better than the analyst consensus.
Realized Career Score and historical re-grades remain available: they are descriptive records of completed careers, not predictions. The full account of what was withdrawn and why is in the methodology; withdrawn endpoints return only when they pass a prespecified, chronology-correct evaluation.
Limits and stability
Rate limits. 60 requests a minute per IP across the public subset, enforced softly: past the limit you get a 429 with a Retry-After header telling you how long to wait — usually a second. That is generous enough for any bot or notebook; if you need sustained volume, email hello@draftanomics.com and we will work something out.
CORS. The public subset is open to every origin (Access-Control-Allow-Origin: *, no credentials), so you can call it straight from a browser app — no proxy needed.
Stability. Consider the endpoints above v0 of the public API. There is no /v0/ in the URL and there will not be — the paths stay where they are. The promise: paths and existing response fields on this page are stable; new fields may be added at any time; anything breaking is announced on /whats-new before it ships. Build parsers that tolerate new keys and you will not be surprised.
Data freshness: consensus and mock-ADP sources refresh on a rolling cadence during the draft cycle; ledger snapshots are immutable once sealed. Every response includes its own dating fields where freshness matters.
