How this service works
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. $0.01 per call. Blockchain IQ.
Output
A JSON array of daily records (up to 365 entries) for the requested token and chain, each containing end-of-day supply, mints, burns, net issuance, and sub-breakdowns by minter type (CCTP, Gateway, other). Control events and blacklist changes are included per day. A separate list enumerates any missing days (never zero-filled). Every day satisfies the reconciliation identity: supply change = mints - burns.
Example use cases
Charting USDC supply growth on Base
“Give me 60 days of daily USDC supply and net issuance data on Base so I can chart how Circle's stablecoin has grown there.”
Auditing EURC mints and burns on Arbitrum
“Fetch the last 30 days of EURC mint and burn activity on Arbitrum — I need the daily figures split by CCTP, Gateway, and other minters.”
Monitoring cross-chain USDC issuance trends
“Show me 365 days of USDC issuance history on Ethereum, including any blacklist or control events and the breakdown of mints by minter type, so I can track long-term trends.”
Technical details
Endpoint
GEThttps://www.blockchainiq.co/api/x402/v1/stablecoins/history?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need granular daily stablecoin supply and issuance data for a specific chain over a historical window, with mint/burn reconciliation and minter-type breakdowns (CCTP vs Gateway). Prefer it over generic market data APIs when you need Circle-native issuance accounting, blacklist/control event history, or cross-chain flow analysis at the daily level for USDC or EURC specifically.
Side effects
- Invalid chain value returns an error (must be ethereum, base, or arbitrum)
- Invalid token value returns an error (must be USDC or EURC)
- days parameter outside 1-365 range returns a validation error
- Payment failure (insufficient USDC balance) results in a 402 response
- Data gaps are reported as missing days, not zero-filled entries
