The missing control plane for AI agent payments. Observe, control, protect, and test agent spending across x402, ACP, AP2, and Visa TAP.

The open authority layer + SDKs for AI-agent payments. Thin Python/TS clients, an MCP server, framework adapters (LangChain/CrewAI/Hermes/OpenClaw/…), and @sardis/reference — a pure policy simulator + AP2/TAP/x402 verifiers showing exactly how Sardis decides if an agent may spend. The hosted engine that moves money is private.
