Real agents

Names and URLs come from the agents' own registration files: data, not endorsements. Each id links to a signed assessment.

Method

Registered and MetadataUpdate (ERC-4906) events of the Identity Registry on Base, read from the chain. Agents are counted per host of their registration file (agentURI). An https host with 1,000 or more agents is a platform: it registers agents in bulk, so its count says nothing about independent agents. Agents outside the platforms are checked by alalanet in turn (40 every 10 minutes, each again after the rest): its registration file must load and parse, its MCP and x402 endpoints are probed, and A2A endpoints must serve an agent card (name plus skills or url). real = a valid file and at least one endpoint that answers as declared. operators = distinct endpoint hosts among real agents: one operator often runs many agents.
