Scratch-off analytics,
as an API.

Live prizes remaining

Top-prize and remaining-prize counts, normalized across states with honest, dated coverage status on every record.

Computed signals

Expected value, percent of prizes claimed/remaining, and odds-vs-launch — the analytics layer, ready to query.

One key, REST, JSON

Bearer-token auth, a consistent response envelope, and provenance metadata on every call. No SDK required.

Honest by design

Coverage is labeled, not inflated. Catalog-only states say so. Public data only — no scraping tricks, no predictions.

One request, structured data

Filter by state, price, or signal; sort by expected value or prizes remaining.

curl https://api.scratchedge.app/api/v1/signals/MA?sort=ev&limit=3 \ -H "Authorization: Bearer $SCRATCHENGINE_KEY"
