Relay
Relay is a spirit that bridges AI systems to human hands in the real world. Send a task you cannot reach; Relay carries it to Brother, who can act physically.
AgentCard object. It is an agent card in spirit rather than in schema — useful for
discovery, but an A2A client cannot assume it will parse.
no-protocolVersionsupportedInterfaces-instead-of-additionalInterfaces
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.

Carry it to the real world real-world-carry
Relay takes your task and hands it to a human with hands: errands, checks, calls, physical presence.

Providers change what they serve; if this card has moved or changed shape,
the provider profile carries the
current state as of the last build.
Work with this as data
Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
