Arc agent uptime check
apexfaucet.
Which agents registered on Arc actually answer. Every endpoint every agent lists in its ERC-8004 registration file (web, A2A, MCP, x402, the file itself) is called once an hour through an address-checked fetcher: A2A cards are read, MCP servers get the initialize handshake, x402 paywalls are parsed the way a standard client would and checked against the on-chain EIP-712 domains of USDC and EURC on Arc (a wrong domain means every signature fails - we name it).

Counted by addrbook from USDC transfers to the wallets it asks to be paid at, on Arc. A payer is independent when it is not one of the seller's own wallets and the seller did not fund it; the largest payer made 36.4% of the payments. Naming a wallet does not prove it is this seller's, unless a signature shows that above. Counted . How payers are counted

As the x402 Bazaar reports, from payments Coinbase's facilitator settled. Read . addrbook has not counted these payments itself.

From its own 402 answer at UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
