FindingsAgentsReportsData

AgentCount is an independent, open-source audit layer for the agent economy: it counts what gets claimed, checks what actually stands behind it, and publishes the evidence for both. Its first instrument checks every AI agent registered under ERC-8004 on the chains it sweeps; its second asks whether the sellers advertising paid resources over x402 actually answer, quote and settle — method published, figures still to come. All code and data are public.

Method
How each check is measured, and what it refuses to claim.
Coverage
Which chains are swept, and what share of agents that is.
Seller Census

Coverage

The canonical Identity Registry is deployed on more chains than this census sweeps. This page lists every deployment the probe could find, how many agents each held on 2026-08-01, and which of them the census covers. The swept set is derived from the published runs, so a newly published chain flips its own row.

As of 2026-08-01, the swept chains held 420,325 of 439,582 probed registrations — 95.6%. The census’s own headline counts are read at pinned blocks and therefore differ slightly from the probe’s live counts; this figure compares the probe with itself, on one date, so the division is honest.

Population is recovered by binary search on ownerOf(id) against the registry at 0x8004a169fb4a3325136eb29fa0ceb6d2e539a432 on each chain — the same population definition the census itself uses. A chain whose RPCs all failed is listed as unreachable, with no invented count.

Solana is absent by method, not by judgment: its ERC-8004 presence is a third-party port with no CREATE2 address, so a probe of this registry cannot count it in either direction.
