# P2Flux

> Non-custodial USDC payments on Base. One-time payments, recurring payments and refunds settle directly to a wallet the merchant controls. There is no P2Flux merchant account, no API key and no payout step.

The P2Flux API has no signup and issues no credentials. The integration endpoints are POST with a JSON body. Requests that act on an existing payment, subscription or refund carry a capability that the API issues and signs with an HMAC. Keep subscription capabilities server-side. Production runs on Base Mainnet at https://api.p2flux.com, and a full test environment runs on Base Sepolia at https://api-test.p2flux.com.
