x402Crypto & web3Community listed · unclaimedAgentHub by Allium150+ chains, in any AI client. Install the Allium MCP server, skill, or CLI in one command — or skip the API key entirely and pay per query in USDC.
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. Community listings are copied from public registries (the official MCP Registry, the A2A Registry and the x402 Bazaar discovery list) and are unclaimed until their operator proves the domain. Checks are our own automated probes, not a guarantee.
