x402-gated Stripe customer data endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com exposes a specific Stripe customer resource (`/api/v1/stripe/customers/164`) behind an x402 paywall. It 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 broader lowpaymentfee.com platform advertises a wide catalog of pay-per-request 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 (`/stripe/customers/164`) is not listed on the site's public catalog; it appears to be a Stripe customer record lookup. No request body schema, response schema, or documentation beyond the x402 challenge is available for this particular resource.
Because the endpoint path references a specific Stripe customer ID (164), it is unclear what data is returned or whether the endpoint is useful in a general-purpose context. The site's docs, pricing, and README pages all render only a "Connect wallet" prompt with no additional documentation. The x402 challenge confirms the endpoint is live and accepting payment negotiations.

Quality
The x402 challenge is live and confirms pricing and network details, but there is no documentation, no request/response schema, and the endpoint references a single hardcoded Stripe customer ID with no explanation of what data is returned. The site's doc pages are empty beyond a wallet-connect prompt.
