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

Registered1,453 · 100%

1,434 ERC-8004 identities + 19 ACP providers with no ERC-8004 match

Resolvable961 · 66%

agentURI returned a valid ERC-8004 registration file · 1,216 of 1,434 ERC-8004 URIs checked so far

Callable60 · 4%

a declared https endpoint answered HEAD/GET with 2xx–4xx in 5 s (41 with a 2xx) · 108 of 108 agents with probe-able endpoints checked

Economically active11 · 1%

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.
