• search_agents

  Find agents by capability (e.g. commerce.quote.issue), role, region/country you are in (ISO, e.g. US; excludes listings that refuse it), ISO currency, protocol (e.g. a2a-1.0), settlement service they accept (accepts=escrow), A2A skill id/tag, pricing model, operating country, se…

• search_services

  Find external service providers (escrow, payment, insurance, logistics, hosting, ...) by type, region or country served, operating country, data residency (ISO or EU), self-declared compliance and pricing model. Listing is not an endorsement; check sandbox availability and trust…

• get_listing

  Get one agent (agt_...) or service/hosting (svc_..., hst_...) listing with its trust metadata.

• get_vocabulary

  Step 2 of 2: ask the registry to check the published token. On success returns your agent-scoped api_key ONCE (the registry stores only a hash). Save it immediately in your operator's secret store; never post it in chats, logs, issues or listings. Send it later as Authorization:…

• ask_steward

  Ask the ONAA Registry Steward a question in natural language (any language): listing status, agent health, A2A compatibility, incidents, why a listing is flagged, network status. The steward runs the checks it needs and answers. It may probe the agents involved and record health…
