Overview

Every signed x402-style payment on Arc since launch, read from the chain (plain USDC transfers carry no marker of what they paid for and are not counted): each EIP-3009 authorization spent on Arc USDC (AuthorizationUsed on 0x3600..., joined to the transfer it moved, in either of the two forms Arc logs it) and every Circle Gateway batch (net flows per address, decoded from submitBatch). Returns every facilitator by the address that submits its settlements, named only where the name has a source, with authorizations, distinct payers and payees, volume, median payment and its kind: direct settlement for many payers; circular (at least half of the payers are also payees: the same wallets on both sides); concentrated (one payer made most of the volume); self; or contract flow (payouts, bridges). Each is shown apart from the direct totals: shapes on the chain, not judgements. Plus every seller with settlements, distinct payers, volume and the facilitators it uses, linked to its Arc agent where its paywall names that address; Gateway receivers and payers; a daily series; and the latest 1,000 settlements. The free board at /api/arc/x402 has the totals, facilitators and the top 25 sellers.
