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 Stripe customer resource (customer ID 110) 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 (USDC uses 6 decimals). No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
The hosting provider, lowpaymentfee.com, advertises a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/crypto data, and utility services — all priced at $0.02 per request. However, this specific endpoint (/api/v1/stripe/customers/110) is not listed on the provider's public landing page among those categories. Its description is simply "Premium API Access," and no further documentation, request schema, or response schema is available. The docs, pricing, and API pages behind the site all render only a "Connect wallet" prompt with no additional content.
Because there is no documentation explaining what data this endpoint returns, what POST body it expects, or how the Stripe customer resource is structured, consumers should treat this as a low-documentation endpoint. The x402 challenge is live and well-formed, confirming the endpoint is operational.

Quality
The x402 challenge is live and well-formed, confirming the endpoint works. However, there is no documentation, no request/response schema, and the specific endpoint is not listed on the provider's own landing page. The purpose and data returned are unclear beyond the generic label "Premium API Access."
