Exposes live circulating supply (total and per-chain), on-chain mint (issuance) events per chain, and the history of independent monthly reserve attestations. No authentication is required; responses are JSON with permissive CORS (Access-Control-Allow-Origin: *) and are cached at the edge (Cloudflare, max-age 300s). This specification was generated by the API Evangelist enrichment pipeline from the endpoints documented in https://loon.finance/llms.txt and the verified live JSON responses on 2026-07-20; it is not published by Loon.'
