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/5`. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 payment challenges settled in USDC on the Base network.
The specific endpoint probed (`/api/v1/stripe/customers/5`) returned 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 across all its endpoints, with no API keys, no rate limits, and no minimum commitments. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages only show a "Connect wallet" prompt), so the actual response schema and behavior of this particular Stripe customers endpoint are unknown. It is unclear what data this endpoint returns or what input it expects beyond a POST body.
