Pay-per-call customer data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at `/api/v1/customers/95` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints use the x402 payment protocol on the Base network, accepting USDC (USD Coin) for payment. The specific endpoint probed serves a "Premium API Access" resource returning JSON via POST.
The platform advertises a flat $0.02 per request across all its endpoints, with no API keys, no rate limits, no minimums, and instant access. The x402 challenge confirms the endpoint is live, requesting a maximum of 20,000 base units of USDC (0.02 USDC = $0.02) on Base, paid to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The payment timeout is 300 seconds.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the `/api/v1/customers/95` endpoint actually returns. The endpoint path suggests customer record retrieval (possibly a demo or sample resource), but the actual payload structure is unknown. The platform lists many other endpoints on its landing page, but none have documented schemas or example responses.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request parameters, response schema, or what the endpoint actually does. Docs pages are empty beyond a wallet connect prompt. Effectively a stub listing.

- —The purpose and response format of /api/v1/customers/95 is undocumented — the path suggests customer data but this is unconfirmed
