Analysis generated from our live index of every ERC-8004 agent we can see on Base, Ethereum, and BNB Chain. Numbers are pulled live; nothing here is hand-curated.
A worked example on agent base/19353: what the free per-agent profile
answers, what the free 200-node graph teaser shows, and what the paid
/v1/intel/peers/{agent_id} and
/v1/intel/graph endpoints add — the ten closest peer agents by capability
overlap, and the full inter-agent payment network in one call.
The six on-chain and off-chain signals that separate a real, usable ERC-8004 AI agent from a paper registration — identity, ReputationRegistry feedback (Sybil-adjusted), x402 and settlement history, cross-chain presence, and live reachability. Vendor-neutral checklist you can apply on any chain.
Five weeks on: the index is bigger, the BNB coverage moat has widened, and almost none of Report 01's headline agents are still Transact-ready. What the current readiness distribution tells us about which agents actually work.
The inaugural census of the ERC-8004 agent economy — the MCP and OpenAPI capability layers, owner identity, the factory-cluster long tail, and what reachability tells us about which agents actually matter.
