Everything the Index publishes is available as plain JSON with CORS enabled — no key, no signup, no rate-limit games. Cite it, chart it, build on it.
| Endpoint | What it returns |
|---|---|
/data/summary.json | The latest run: aggregate stats (average score, llms.txt adoption, blocking and closed percentages, paradox count) plus the full ranked leaderboard with score, grade, posture, and signal flags per domain. |
/data/history/{YYYY-MM-DD}.json | One snapshot per weekly run — the adoption time series. Week zero is 2026-08-27. |
Raw per-site check results live in the repository under data/index/results/, one JSON file per domain, refreshed by the same public CI run. The evaluator itself is ~300 lines of dependency-free TypeScript — reproduce any number on this site with plain HTTP requests.
