A2A Agent Card · Agentcard

Agentcard

Issue virtual Visa cards for AI agents. Fund a card with a fixed USD budget, hand the credentials to an agent via MCP, and spend anywhere Visa is accepted. Single-use by design — the blast radius of any misstep is capped at the card balance.

⚠ Agent card, not A2A. Agentcard serves a machine-readable agent manifest at the A2A discovery path, but it fails a structural check in the A2A 1.0.0 AgentCard object. It is an agent card in spirit rather than in schema — useful for discovery, but an A2A client cannot assume it will parse.

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.
