AgenstryAgenstry● healthy
Independent evidence infrastructure for the agent economy — measures which public A2A agents and MCP servers genuinely exist, respond, are operated by a verifiable legal entity, and get paid. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent itself, scores them on a published 9-criterion conformance scale, verifies the provider against GLEIF LEI and seven other business registries, monitors drift over time, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Ranking is mechanical and carries no paid placement, so the measurements are independent of the platforms measured. Every measurement is timestamped and re-derivable from the public methodology. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call through Stripe. Exposed as A2A agent, MCP server, and REST API.
