A2A Agent Card · Benchmark Email

Benchmark Email API

Benchmark Email serves a real A2A Agent Card from its developer documentation host, developers.benchmarkemail.io. The card was fetched anonymously and saved verbatim to a2a/benchmark-email-agent-card.json. It advertises one skill that points at a provider-published Agent Skill document, and declares HTTP+JSON as its preferred transport.

✓ Conformant with A2A 1.0.0. This card passes every structural check in the A2A specification’s AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.

Discovery

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.

Work with this as data

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.
