How this service works
Parameter-free Circle USDC and EURC snapshot on Ethereum, Base and Arbitrum from the token contracts: total supply, 1/7/30-day supply change, 7-day net issuance split CCTP / Gateway / other minters, mint and burn counts, paused flag, implementation and last upgrade, role holders, blacklist count and 30-day changes, last control event. Use to watch stablecoin supply and freeze risk. Refreshed daily; never sold stale. JSON, no API key. $0.01 per call. Blockchain IQ.
Output
A JSON object containing: total USDC and EURC supply per chain (Ethereum, Base, Arbitrum), 1/7/30-day supply change figures, 7-day net issuance broken down by CCTP, Gateway, and other minters, mint and burn counts, a paused boolean flag, current implementation address and last upgrade timestamp, role holders, blacklist count with 30-day delta, and the most recent control event. Data is refreshed daily.
Example use cases
Stablecoin supply risk dashboard
“Pull me the current USDC and EURC supply data including total supply, 7-day and 30-day changes, paused status, and the latest control or freeze event — I want to monitor for any sudden supply shocks or freeze risk across Ethereum, Base, and Arbitrum.”
DeFi protocol issuance analysis
“How much USDC has been net-issued in the last 7 days, and what share came through CCTP versus Gateway versus other minters? I'm trying to understand where new supply is coming from on Base and Arbitrum.”
Compliance and blacklist monitoring
“What's the current USDC blacklist count and how has it changed over the past 30 days? Also tell me who the current role holders are and whether there have been any recent control events I should know about.”

Endpoint
GEThttps://www.blockchainiq.co/api/x402/v1/stablecoins?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, analyst-curated daily snapshot of USDC and EURC stablecoin supply, issuance, and control risk across Ethereum, Base, and Arbitrum in a single parameterless call — especially when monitoring freeze risk, blacklist trends, or supply-side issuance flows without needing to query raw blockchain contracts directly.
Side effects
- Payment not processed — 402 response if x402 payment is not attached or fails
- Stale data — data is refreshed daily so intraday supply changes will not be reflected
- Network or upstream error — 5xx if blockchain node data is temporarily unavailable
- Rate limiting — excessive calls in a short window may be throttled
