Hilt Pay Agent Gateway
Agent-readable access to Hilt Pay: x402 V2 paid requests with Solana USDC settlement, atomic metered usage, durable entitlements, receipts, signed webhooks, subscription state, sandbox bootstrap, and live API-plan activation.
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.
