name: P2Flux API description: >- Non-custodial USDC payments API on the Base blockchain. Provides REST endpoints for one-time USDC payment intents with on-chain verification, recurring/subscription payments with merchant-triggered charges, and refunds. Payments are authorized per-request via HMAC-signed capabilities plus the payer's EIP-712 wallet signature — no signup, no dashboard, no issued credentials, and no custody of funds. url: https://raw.githubusercontent.com/api-evangelist/p2flux-api/refs/heads/main/apis.yml image: https://p2flux.com/assets/apple-touch-icon.png created: '2026-09-15' modified: '2026-09-15' specificationVersion: '0.21' tags: -
