Seller payment record: who has paid an x402 seller in USDC

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

See whether other buyers pay an x402 seller before you do: every USDC transfer into its payout wallet over the last 1-7 days from public logs on Base, Ethereum, Arbitrum, Optimism or Polygon, with payments, distinct and repeat payers, total and median amount, first and last payment and top payers. Give the payout wallet or the paid endpoint's URL. Counts all USDC received, x402 or not. Use before the first payment to an unfamiliar seller.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/x402/seller-record?address=0x6293ded2684F1A76E26bEcef87c137D691Fbf800"

Or one of your 3 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/x402/seller-record?address=0x6293ded2684F1A76E26bEcef87c137D691Fbf800&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.
