The payment gateway for the agentic economy. Accept payments from AI agents. Add a few lines of code. Settle instantly in USDC.
Agent → 402 Challenge → Sign USDC Transfer → PincerPay Facilitator → Blockchain → Merchant
PincerPay is a non-custodial x402 facilitator. When an AI agent hits a merchant API and gets HTTP 402, the agent signs a USDC transfer. PincerPay verifies the signature, broadcasts to the blockchain, and confirms settlement.
