1. What is P402 Router and how does its payment routing system work?
Answer: P402 Router is a routing control plane that manages x402 crypto micropayments by selecting payment facilitators, verifying transactions, enforcing spending policies, recording payment traces, and securely settling USDC or USDT payments on the Base blockchain.
2. Which cryptocurrencies and blockchain networks does P402 Router currently support today?
Answer: P402 Router supports USDC and USDT for micropayment settlement on the Base blockchain, providing secure, low-cost, and efficient payment processing for APIs and autonomous agent applications.
3. How does P402 Router improve reliability for paid API transaction processing?
Answer: The platform intelligently selects healthy payment facilitators, automatically reroutes failed requests, applies policy controls, and continuously monitors payment performance to ensure dependable transaction processing for paid endpoints.
4. Why might payment requests still return HTTP 402 after payment submission?
Answer: Common reasons include invalid payment signatures, insufficient payment amounts, unsupported headers, inadequate wallet balances, or compliance-related payment restrictions that prevent successful transaction verification.
5. What spending controls and security policies are available within P402 Router?
Answer: P402 Router supports configurable spending budgets, request rate limits, route caps, denial rules, and policy enforcement to protect payment systems while maintaining secure transaction processing.
6. What purpose does Bazaar serve within the P402 Router payment ecosystem?
Answer: Bazaar provides machine-readable endpoint metadata that helps developers and autonomous agents discover payable services, pricing information, routing details, and runtime availability efficiently.
7. Can developers integrate P402 Router with existing paid API infrastructures easily?
Answer: Yes. Developers place P402 Router between paid endpoints and payment facilitators, allowing seamless payment verification, routing, settlement, and policy enforcement without redesigning existing API workflows.
8. Which applications benefit most from implementing P402 Router payment infrastructure today?
Answer: P402 Router is ideal for pay-per-call APIs, AI agent commerce, internal chargeback systems, premium data pipelines, and developer platforms requiring scalable crypto micropayment processing.
Monetizes pay-per-call APIs through secure crypto micropayments with intelligent routing, policy enforcement, and reliable transaction settlement.
