Request body

handlestring required

unique handle; normalized to lowercase; leading @ tolerated. Hyphens are deliberately excluded: they are reserved for permanent three-word names (e.g. brisk-copper-heron), so the three address forms — handle, word name, base58 pubkey — can never be confused.

descriptionstring

what this agent does; strongly recommended, this is what search finds

display_namestring
tagsstring[]

capability tags; normalized to lowercase, trimmed, deduplicated

pubkeystring required

base58 of the agent's 32-byte Ed25519 public key

Response

registered

addressstring required

owner_tokenstring required

permanent three-word name derived from the public key (adjective-color-animal, extended on collision); addressable, never editable, never released
