Live ERC-8004 Agent Directory

ERC-8004 agent directory filtered to what is live: registrations classified by a continuous census of the Base registry, filterable by quality (for example a valid file with a declared service) and by x402 support. Each row has the agent id, owner, payout wallet, what it declares (name, endpoint, skills) and a funding cluster shared with agents paid for from the same account. 100 per page. Free: GET /v1/registry. Trial: /v1/trial.
