Relevance

The protocol draft defines an Agent Discovery Service Protocol in JSON-LD, with active discovery at https://{domain}/.well-known/agent-descriptions and an Agent Description "Information" that covers "products, or services". The use_case.html draft includes a hotel booking scenario (Personal Agent, Search Agent, hotel Service Agent) with the requirement "Agent Transactions". The agent identity draft uses a Decentralized Identifier (DID) URL as the HTTP signature keyid with RFC 9421 and RFC 9530.
