P402 Router | x402 Payment Infrastructure

P402 Router is a sophisticated routing control plane built to operationalize and scale x402 (HTTP 402 Payment Required) payments for paid endpoints and agent stacks. The x402 ecosystem is still fragmented and unstable, and P402 Router tackles that head-on by sitting between paid endpoints and payment facilitators, giving teams a dependable foundation for real-time crypto micropayments.

For every incoming request, the Router evaluates the call, selects the optimal acceptance options, routes verification and settlement, and enforces critical policies such as spend controls and rate limits. That means you can monetize pay-per-call APIs without hand-wiring payment logic into every endpoint, while agents get predictable, policy-guarded access to paid resources.

Settlement is trustless by design, using USDC and USDT on the Base blockchain with a low flat fee of just 1%. Whether you are running a high-volume pay-per-call API or enabling agent-to-agent transactions, P402 Router delivers the routing infrastructure to make x402 payments dependable at scale.
