Discovery
A2A agent card
An A2A-compatible agent card so generic A2A tooling can find the seller. The x402 extension is marked required and carries the payment network, the facilitator URL and the accepted asset symbols; a second, optional extension points at the full Agora402 manifest. Skills mirror the manifest endpoints. Free, unauthenticated.
