If you're building AI agents that need to handle micropayments on Base, this server gives Claude direct access to x402 payment routing and settlement. It exposes seven core skills: listing facilitators, getting route quotes with fee comparisons, verifying payment intents, fetching settlement receipts, and running budget simulations. The underlying SDK talks to NexFlow's API for payment verification and batch settlement via Merkle proofs on the AtomicBatchSettlement contract. You'd reach for this when gating API access behind pay-per-call pricing or building agents that need to pay for third-party services autonomously. The repo includes a Lambda@Edge example for dropping 402 gating in front of CloudFront without touching your backend.
