x402-gated Stripe customer data endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 143) 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 hosting site lowpaymentfee.com advertises a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (/api/v1/stripe/customers/143) is not among the publicly documented APIs on the site's landing page. The x402 challenge for this endpoint advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site's stated flat pricing.
Documentation is extremely sparse. The /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what data this Stripe customer endpoint actually returns. The endpoint is live (returns a valid 402 challenge), but the lack of documentation makes it difficult to know what to expect from a successful paid request.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no request/response schema, and no meaningful documentation beyond a wallet-connect prompt. The specific endpoint (/stripe/customers/143) is not listed among the site's advertised APIs, making its purpose unclear. This is effectively a stub listing.
