Pay-per-call Stripe customer data endpoint on Base via x402, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to Stripe customer data (specifically customer ID 111) via the x402 payment protocol. It accepts POST requests and charges 0.02 USDC per call on the Base network. No API keys or rate limits are required — payment is handled inline via the X-PAYMENT header using the x402 exact scheme.
The hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. This specific endpoint appears to proxy or wrap Stripe's customer retrieval functionality, though the exact response payload is undocumented. The x402 challenge confirms the endpoint is live, settles in USDC (contract 0x8335…2913 on Base), and pays to address 0x1A2B…85F3.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response, and no description of what fields are returned for a Stripe customer lookup. Buyers should treat this as a minimally documented endpoint.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no example responses, and the actual functionality behind 'Stripe customers/111' is unexplained. Effectively a stub listing.

- —No OpenAPI or response schema provided
- —Unclear what data is returned for a Stripe customer lookup
- —Endpoint path includes a hardcoded customer ID (111) — unclear if this is parameterized or fixed
