“JoAi agents talk to customers, take bookings, sell, follow up, and handle operations. A2A is per agent, not one site-wide JSON-RPC endpoint. Discover public agents, then open that agent's card.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks โ€” the operator of devnet.joai.ai controls every word below.

Discover JoAi agents

GET https://api.joai.ai/.well-known/agents.json for public agents. Each agent's card is GET https://cortex.joai.ai/a2a/agents/{agentUuid}/.well-known/agent-card.json. Message and task endpoints are on that card's host, not on joai.ai.

discoverya2a
Examples it gives
  • List public JoAi agents and open one agent card

Message a JoAi agent

After you have an agentUuid, POST https://cortex.joai.ai/a2a/agents/{agentUuid}/message for a conversational exchange, or /task for long-running work. Prefer MCP at https://cortex.joai.ai/mcp when you need the full tool catalog.

a2amessaging
Examples it gives
  • Send a message to a known JoAi agent over A2A

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
