Paubox API Docs
Paubox serves an A2A Agent Card from its documentation host. The card is scoped to the documentation site rather than to the API hosts: name, url, provider and documentationUrl all point at https://docs.paubox.com/, and its single skill links to a Paubox-authored Agent Skill markdown file served from the same host. No card is served on www.paubox.com, api.paubox.com or mcp.paubox.com (all 404).
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.
