x402-gated Stripe customer endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe customer resource at `/api/v1/stripe/customers/31`. It is part of a broader platform offering dozens of pay-per-call API endpoints across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated behind x402 payment challenges settled in USDC on the Base network.
The specific endpoint probed (`/api/v1/stripe/customers/31`) returns a live 402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`, with a 300-second timeout. The endpoint accepts POST requests and returns `application/json`.
The platform advertises a uniform $0.02/request pricing model with no API keys, no rate limits, and no minimum commitments. However, documentation pages (`/docs`, `/pricing`, `/api`, `/README`) all render only a "Connect wallet" prompt with no substantive content, so the actual behavior and response schema of this particular Stripe customers endpoint are unknown. It is unclear what data is returned or what input parameters are expected beyond a POST body.
