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 the ERC-8004 identity registries on Base and Ethereum mainnet and of Virtuals ACP on Base — not anyone's self-reported count.

The honest funnel

Registered152,334 · 100%

151,893 ERC-8004 identities + 441 ACP providers with no ERC-8004 match

Resolvable1,368 · 1%

agentURI returned a valid ERC-8004 registration file · 7,542 of 151,893 ERC-8004 URIs checked so far

Callable173 · 0%

a declared https endpoint answered HEAD/GET with 2xx–4xx in 5 s (86 with a 2xx) · 257 of 257 agents with probe-able endpoints checked

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.
