Stablecoin supply: USDC and USDT on 5 networks

$0.01 per call · failed calls are never charged · no account or API key needed

Live total supply of USDC and USDT on Ethereum, Base, Arbitrum, Optimism and Polygon, read from each token contract (totalSupply), per network and summed per token, plus the grand total. A network whose nodes do not answer is listed with an error instead of failing the call. Use to track stablecoin issuance, liquidity on a chain or mints and burns over time.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/stablecoin/supply?token=both"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/stablecoin/supply?token=both&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
