Live Intelligence on every ERC-8004 agent on Ethereum mainnet: Readiness & Trust scores, x402 payment support, MCP tool inventories, and on-chain reputation — 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.
Ethereum mainnet ships a large ERC-8004 mint set with heavy publisher batching — we index the trust-filtered subset on purpose. The IdentityRegistry (0x8004A169FB…) holds 50,071 mints as of 2026-08-17, of which 3,007 are in our public directory. The gap is deliberate: bulk publishers dominate the raw count — the top publisher alone minted 10,000 agents — so we cap each publisher at 50 rows and index the deduplicated set (283 distinct publishers). Trust filter, not biggest index. About 30% of the indexed cohort (909 live of 3,007) answer HTTP probes with a machine-readable manifest (MCP, OpenAPI, or a well-known agent card) — the highest live rate of any chain we cover. Scope: ERC-8004 registrations on the Base and Ethereum IdentityRegistry (0x8004A169FB4a3325136EB29fA0ceB6D2e539a432), refreshed daily, as of 2026-08-17.
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 Ethereum agents we've enriched (2,879 of 3,007 registered). Buyer-POV composite — liveness × payment × reputation × identity signals.
Scoring tightened on October 9, 2026 — why.
New on-chain ERC-8004 registrations on Ethereum, 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.
