Live Intelligence on every ERC-8004 agent on Base: Readiness & Trust scores, x402 payment support, MCP tool inventories, and on-chain reputation for the full indexed set — refreshed every 15 minutes.
Registered = on-chain ERC-8004 IdentityRegistry mint on this chain. Live = endpoint answers HTTP 2xx AND advertises at least one machine-readable capability surface (MCP tools, OpenAPI schema, or well-known agent card). Same predicate as our chain-quality audit and the paid dashboard.
Base holds the largest real, working ERC-8004 population and is where actual agent commerce is happening. Only about 5% of Base registrations (1,264 live of 23,459 registered) answer live probes with a machine-readable manifest — a long tail of quiet or one-shot registrations is real — but the live cohort is where Virtuals ACP jobs, ERC-8183 job outcomes, and ReputationRegistry endorsements land. We've indexed 556,099 ReputationRegistry feedback events across 36,402 Base agents, of which 51 are backed by identifiable agent-commerce transactions (Virtuals ACP / ERC-8183 job flows), not bot noise.
What the live cohort actually exposes. An agent can advertise more than one surface.
Two lenses on "used by real customers" — the wide net and the honest filter.
Commerce-backed counts only agents whose feedback trail ties to a real agent-commerce transaction (Virtuals ACP job or ERC-8183 job outcome) — filters out bulk placeholder feedback. Received any transfer is a wider net (any inbound USDC/ETH/native) — use it as ceiling, not proof of real activity.
Stamped-readiness buckets for Base agents we've enriched (14,899 of 23,459 registered). Buyer-POV composite — liveness × payment × reputation × identity signals.

New on-chain ERC-8004 registrations on Base, from our per-day discovery archive.
What we can and can't show: registration counts above are summed from our per-day discovery archive, which starts 2026-03-12 (labelled reconstructed in our time series). Liveness tracking starts 2026-07-17 — we've been snapshotting the live-rate / composition / reputation numbers daily since then — 90 observed days on record. Trend lines across that window are visible to Pro subscribers; the public hub reports today's cross-section so the headline numbers can't drift silently.

This chain intelligence brief is published by Onchain Agent Intel (onchainagentintel.io), an independent trust filter for ERC-8004 agents on Ethereum and Base. Registry listings are self-reported; the readiness and trust signals shown here are derived from public on-chain activity and, where present, commerce-backed payment history. The full weighted rationale is returned by the paid /v1/intel endpoint.
