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.
