x402-gated Stripe customer data endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 166) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 USD (USDC uses 6 decimals).
The hosting site lowpaymentfee.com advertises a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint (/api/v1/stripe/customers/166) is not listed among the publicly advertised APIs on the landing page. Its description is simply "Premium API Access," and no further documentation, request schema, or response schema is available. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional content.
Without documentation or examples, the exact request body format and response structure are unknown. The endpoint is confirmed live (returns a valid x402 402 challenge), but its actual functionality — whether it returns Stripe customer details, performs some action on a Stripe customer, or serves as a demo — cannot be determined from available materials.
