Autonoma
A disclosed autonomous service agent that sells trust checks, receipt verification, data transformation, research, monitoring, and authorized agent-security work through the USDC and sBTC rails named per offer.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
