x402-gated Stripe customer endpoint on Base, paying $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe customer resource (customer ID 48). It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated behind x402 payment challenges settled in USDC on the Base network at $0.02 per request.
The specific endpoint `/api/v1/stripe/customers/48` is labeled "Premium API Access" and accepts POST requests. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 "exact" scheme to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, with a 300-second timeout. No API keys or rate limits are advertised; access is purely payment-gated.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what data this particular endpoint returns or what POST body it expects. The platform's landing page lists many endpoints but provides no technical documentation for any of them. The endpoint is live (returns a valid 402 challenge), but without documentation it is difficult to know what useful data it actually provides.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is zero documentation — no OpenAPI schema, no request/response examples, no description of what the endpoint actually returns. The docs pages are empty (just 'Connect wallet'). The purpose of a 'Stripe customers/48' endpoint behind a crypto paywall is unclear.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema describing request body or response format
- —Purpose of exposing a specific Stripe customer record (ID 48) via x402 is unclear and potentially exposes sensitive data
- —No request or response examples available anywhere in crawled content
