P402 Router | x402 Payment Infrastructure
What is P402 Router | x402 Payment Infrastructure?
P402 Router is a sophisticated routing control plane designed to operationalize and scale x402 (HTTP 402 Payment Required) payments for paid endpoints and agent stacks. It addresses fragmentation and instability in the x402 ecosystem by sitting between paid endpoints and payment facilitators. The Router evaluates requests, selects optimal acceptance options, routes verification and settlement, and enforces critical policies like spend controls and rate limits. It facilitates trustless micropayment settlement using USDC and USDT on the Base blockchain with a low 1% flat fee, making it ideal for high-volume pay-per-call APIs and agent-to-agent transactions.
How to use P402 Router | x402 Payment Infrastructure?
To use the P402 Router, integrate it between your paid endpoints and payment facilitators. The process follows the standard x402 flow, enhanced by the Router's controls: 1. Server returns HTTP 402 with the PAYMENT-REQUIRED header (specifying payment requirements). 2. Buyer (typically an agent) retries with the PAYMENT-SIGNATURE header (including the signed payment payload). 3. The Router routes the verification and settlement through the optimal facilitator, records a detailed DecisionTrace, enforces policies (budgets, caps), and settles the payment in USDC/USDT on Base. Access requires submitting a 'Request Access' form to join the router validation network.
