Api Endpoint

USDC & EURC Issuance History

Daily Circle USDC or EURC history for one chain (Ethereum, Base, Arbitrum), up to 365 days: end-of-day supply, mints, burns, net issuance split CCTP / Gateway / other minters, control events and blacklist changes. Every day reconciles exactly (supply change = mints - burns); missing days are listed, never zero-filled. Use to chart stablecoin issuance and cross-chain flows. JSON, no API key. $0.02 per call.
