P402 Router | x402 Payment Infrastructure

Say you run an API that charges a few cents per call and want AI agents to pay for each request automatically.

P402 Router handles that job.

It is a routing control plane for x402 (HTTP 402 Payment Required) micropayments on the Base blockchain, sitting between your paid endpoints and the payment facilitators that verify and settle transactions.

P402 Router evaluates each incoming request, picks an acceptance option, routes verification and settlement, and enforces spend controls and rate limits.

Payments settle in USDC and USDT, with a flat 1% fee.

That makes it a fit for high-volume pay-per-call APIs and agent-to-agent payments.

The selling point is reliability: the x402 ecosystem is fragmented and unstable, and P402 Router is meant to absorb that so your endpoints do not have to.
