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 141) 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).
The hosting site lowpaymentfee.com advertises a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/crypto 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/141) is not listed among the publicly advertised APIs on the landing page, and its exact response payload is undocumented. The title "Premium API Access" and the Stripe-related URL path suggest it returns Stripe customer data, but no schema or example response is available.
The endpoint is confirmed live: the probe received a proper HTTP 402 challenge with a well-formed x402 v1 payment envelope. Documentation beyond the landing page is essentially empty (all subpages just show "Connect wallet"), so the actual request format and response structure remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no request/response schema, and the endpoint is not listed among the site's advertised APIs. The docs, pricing, and API pages are all blank beyond a wallet-connect prompt. The actual functionality behind this specific Stripe customer endpoint is unverifiable.
