AgentCount

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.

Findings
What the sweeps found, one chain at a time.
Agents
Every agent counted, searchable, each with its own record.
Reports
Written analysis of a sweep, dated and cited.
Data
The archives — download any run and recompute it.
Reference
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
The second instrument: who actually sells over x402.

Agents

Every agent this census has read, with all seven checks shown side by side. Search by name, description or owner address, and tick check filters to combine conditions — the filter lives in the URL, so a filtered view is a link you can send.
