Wallet balance lookup, EVM: native coin and USDC balance on 5 networks in one call

$0.002 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Wallet balance lookup for any EVM address: the native coin (ETH, POL) and USDC balances on Base, Ethereum, Arbitrum, Optimism and Polygon in one call, read live from each network, with the USDC total. Use to check what a wallet holds before a payment, bridge or airdrop, or to confirm that funds arrived.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/wallet/balance?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/wallet/balance?address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045&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.
