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

Registered2,611 · 100%

2,588 ERC-8004 identities + 23 ACP providers with no ERC-8004 match

Resolvable1,055 · 40%

agentURI returned a valid ERC-8004 registration file · 2,542 of 2,588 ERC-8004 URIs checked so far

Callable93 · 4%

a declared https endpoint answered HEAD/GET with 2xx–4xx in 5 s (51 with a 2xx) · 141 of 141 agents with probe-able endpoints checked

Economically active12 · 0%

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.
