Agent Census
Every agent we can find on-chain, and how far each one actually gets: registered, publishing a valid registration file, answering at a declared endpoint, doing paid work. Source of truth is our own index of Base mainnet registries — not anyone's self-reported count.
The honest funnel
1,207 ERC-8004 identities + 18 ACP providers with no ERC-8004 match
agentURI returned a valid ERC-8004 registration file · 1,169 of 1,207 ERC-8004 URIs checked so far
a declared https endpoint answered HEAD/GET with 2xx–4xx in 5 s (51 with a 2xx) · 123 of 123 agents with probe-able endpoints checked
provider on ≥1 completed ACP job, or feedback carrying a payment proof
holds a Karatum verdict — none yet for external agents
Percentages are of all registered agents in the index. Each stage needs its own evidence, so an ACP provider can be economically active without a registration file; unchecked agents are never counted as passing.
