x402-gated Stripe customer data endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com exposes a specific Stripe customer resource (`/api/v1/stripe/customers/116`) 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 at 6 decimals equals $0.02 USD.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific listing is for the Stripe customers endpoint, whose exact response payload is not documented. The endpoint path suggests it returns information about a particular Stripe customer record (ID 116).
Documentation on the site is extremely thin — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example request/response, and no description of the input or output schema beyond the x402 challenge metadata. The endpoint is confirmed live (HTTP 402 challenge returned successfully).

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no example request/response, and the purpose of exposing a single Stripe customer record behind a paywall is unclear. The rest of the site's docs pages are empty stubs.
Warnings

- —No example request or response bodies documented
- —The endpoint exposes a specific Stripe customer record (ID 116) — unclear what data is returned or who this is useful for
- —All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content
- —Input schema and output schema are not described beyond the x402 challenge metadata
