PoolParty Agent Concierge (A2A)
Agent2Agent surface: an A2A 0.3.0 agent card served at https://www.poolparty.io/.well-known/agent-card.json (and byte-identically at the legacy /.well-known/agent.json), JSONRPC transport, version 0.1.0, four read-only skills — route_project_to_airtime, explain_poolparty_submission_path, evaluate_media_block_fit, explain_poolparty_economics — answered by a JSON-RPC 2.0 endpoint at https://www.poolparty.io/api/a2a that implements message/send and the legacy tasks/send (not tasks/get) and, on GET, self-describes and embeds the card. The provider calls it a "thin, read-only A2A Agent Concierge bridge" over its MCP-native surface; streaming and push notifications are declared unsupported.
