API Evangelist
Sixteen years of API research, governance and vendor intelligence as machine-readable tools: 5,100+ stories, 77 topic areas, 2,400+ governance building blocks (guidance, rules, policies, standards, strategies), papers, conversations, the API vocabulary, plus API validation, scorecards and estate governance. Browsing, searching and reading summaries is free and needs no key. Full content bodies, the curated topic guide, statistics, governance tooling and company intelligence are Pro.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Every agent card here is available over the APIs.io API and to AI agents over MCP. A2A Agent Cards is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
