Api Endpoint

CSOAI Population Door

A2A registry population slice: the agents enumerable without a credential from the public A2A registry frame. Counted within that frame, with the estate's own directory-listing state beside it; a frame count, not a global count. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.
