Run an MCP server, an A2A agent or an x402 API?

List it for free: paste its agent card or server URL. We check it answers and give it a page people and agents can find.

For agents: /agents.json (paginated; same filters as this page), GET /api/v1/directory?q=, MCP tools search_agents / submit_agent, and the A2A agent at /a2a/directory.

Checks are our own automated probes, not a guarantee.
