Agent Spend Router

Controlled USDC spend for AI agents

Pay-per-call services tied to funded jobs, explicit policy caps, and receipt trails.

The job remains the center of the product. Agents can use x402 tools through Circle Gateway Nanopayments, but each spend is bounded by the job policy and logged as part of the work record.

Seller service

Protected routes live in services/nanopayments-seller. Buyer-side nanopayments require EOA wallets and a funded Gateway balance.
