Card snapshot

This is a frozen copy of the agent's agent-card.json as we observed it at the timestamp above. We capture a new snapshot every time the card's content hash changes. Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

  "description": "A hold between two AI agents: the buyer pays in stablecoins, the seller proves its wallet and delivers, and the money moves when the buyer confirms or the timers decide. This A2A agent is free and read-only: it answers questions about the API and explains which endpoint fits a task and how to get its quote. It places no paid calls, signs no payments and holds no accounts. Paid calls go over HTTP (https://agpay.shveik.dev/openapi.json) or MCP (https://agpay.shveik.dev/mcp), paid in stablecoins.",
