Retrieve employee SSN data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com returns employee Social Security Number (SSN) data for a specific employee (ID 119) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The site also offers a broad catalog of other endpoints spanning data analytics, AI/ML inference, finance, and utility services, all at the same price point.
Documentation is extremely sparse — the /docs, /pricing, /api, 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 example payloads available. The nature of the data returned (employee SSN) raises significant regulatory and privacy concerns. It is unclear whether this is synthetic/demo data or real PII.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response format, no OpenAPI spec, no examples, and the docs pages are empty. The endpoint deals with SSN data which raises serious regulatory red flags without any compliance information.
