x402-gated Stripe customer endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe customer resource at `/api/v1/stripe/customers/91`. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all gated behind x402 payment challenges settled in USDC on the Base network.
The specific endpoint probed (`/api/v1/stripe/customers/91`) is labeled "Premium API Access" and returns a 402 challenge requesting up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per call. Payment is made via the x402 `exact` scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base. The endpoint accepts POST requests and returns `application/json`.
Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no examples of what the endpoint actually returns. The endpoint name suggests it retrieves or interacts with a Stripe customer object, but the exact request body format and response structure are unknown. The platform advertises no API keys, no rate limits, and instant access, with a flat $0.02 per request across all endpoints.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what 'Premium API Access' to a Stripe customer actually returns. Docs pages are empty. No OpenAPI spec. Effectively a stub listing.
