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 187) 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 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 x402 challenge for this specific endpoint shows a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02 USD, consistent with the site's advertised pricing.
Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no explanation of what data the Stripe customers endpoint actually returns or what POST body it expects. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to determine the actual functionality or expected input format.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no explanation of what the endpoint actually returns. The purpose ('Stripe customers/187') is opaque without further context.
