Buy Latitude 10 Agent Spend Guard for Node.js

For Node.js: let your agents pay for things without handing them your wallet: a TypeScript library and an optional server that sit in the payment path of x402 (Base and other EVM chains, Solana), MPP (Tempo, and Stripe cards via Shared Payment Tokens) and L402 (Lightning), over HTTP and MCP. Per-payment caps, hourly/daily/monthly budgets per agent and in total, per-merchant and per-tool limits, network, token and recipient lists; budgets reserved atomically before signing (memory, SQLite or Postgres), so concurrent payments never overspend; human approvals above a threshold (callback, or a queue with Slack links); a freeze switch and velocity auto-freeze; reconciliation of unknown outcomes from the chain; a hash-chained audit log. Server mode keeps keys off the agent’s machine (agents hold tokens). Local keys or your own KMS/MPC signer. Includes a setup wizard (node setup.mjs) with an overspend demo, a CLI, Docker and Fly.io files, and an Agent Gateway paymaster.
