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 record (ID 95) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The provider site lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per call. No API keys or rate limits are advertised; access is granted purely via the x402 payment header. The site root returns HTTP 200 and the x402 challenge is live.
However, this specific endpoint purports to serve personally identifiable information (an employee's SSN). There is no documentation explaining the data source, whether this is synthetic/demo data, or what legal framework governs its use. The docs, pricing, and API pages on the site are essentially empty (showing only a "Connect wallet" prompt). No OpenAPI schema, request/response examples, or data provenance information is available. Users should exercise extreme caution given the sensitive nature of SSN data and the complete lack of documentation about its origin or legitimacy.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is zero documentation, no OpenAPI schema, no request/response examples, and the endpoint serves highly sensitive PII (SSN) with no explanation of data provenance or legal compliance. The docs/pricing/API pages are empty stubs.
