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.

Sift sift
Use when ingesting telemetry data, analyzing hardware test runs, detecting anomalies with rules, comparing runs against baselines, creating derived signals, managing multi-run review campaigns, or exporting data for external analysis. Sift is a telemetry platform for teams working on complex machines (rockets, aircraft, robots, manufacturing systems) who need to move from raw data to confident decisions.

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.
