The agent economy on Arc, mapped: every agent in the ERC-8004 identity registry that publishes a registration file (summary.registered and summary.withRegistrationFile carry both counts live; the registry grows, so no count is quoted here) with its name, what it does, the services it sells, its owner, its registration file and whether it accepts x402 payment — plus ?q= to search by capability ('audit', 'escrow', 'data').
