Pay-per-call customer data API on Base via x402 — $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a "Premium API Access" resource at the path `/api/v1/customers/32`. It is part of a broader platform offering multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request and settled via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/customers/32` accepts POST requests and returns JSON. Payment is handled inline: callers must include an X-PAYMENT header with a valid x402 payment proof. The maximum amount required per call is 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, with a timeout of 300 seconds.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, 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/32` endpoint actually returns. The endpoint name suggests customer record retrieval, but the exact data schema and input parameters are unknown. The platform advertises no API keys, no rate limits, and instant access.

Quality
The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC per call on Base). However, there is no OpenAPI schema, no request/response examples, and no documentation beyond a landing page listing. The actual purpose and data returned by /api/v1/customers/32 are unknown, making this effectively a stub listing.
