Launch-Quality Grade API

A free, CORS-open JSON API for the live A–F fair-launch grade of any Kaspa KRC-20 token or KRC-721 collection — the same grade shown across the Linkrra dashboard, computed from public on-chain data (Kasplex holder distribution + KaspaCom marketplace activity).

Notes

• Real data only. A token/collection with no on-chain holder array returns { "graded": false, "reason": … } — never a faked score. Undeployed / unknown tickers return 404.
• No divergence. The grade is computed with the exact same scoring model as the in-app drawer, embed badge, compare, leaderboard and report pages — the API grade can never differ from any other surface.
• Open & cached. Access-Control-Allow-Origin: *, short CDN TTL. No key, no auth, no rate-limit — just GET it.
• Pillars are 0–100: Fairness (anti-concentration), Adoption (holder base), Liquidity (marketplace activity). score is their weighted composite (45/35/20); grade is A≥85 · B≥70 · C≥55 · D≥40 · F.
