AgentProbe Counts the AI Agents That Actually Answer

Field notes

AgentProbe aggregates 37 public sources into a registry census, then tests remote endpoints rather than treating directory listings as evidence of operation. The page reports 103,478 known endpoints and 901,714 listings, with 103,372 endpoints probed and 30,180 marked alive. Its interface exposes lookup, source and overlap views, methodology, standards, and links to stats, OpenAPI, agent-card, and other machine-readable files. The operator is identified as Michael Paris; bulk data is stated not to be public.
