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 159) behind an x402 paywall. It accepts POST requests and settles payments in USDC on the Base network using the x402 "exact" payment scheme.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers various pay-per-call APIs across data analytics, AI/ML inference, finance, and utility categories — all priced at $0.02 per request with no API keys, no rate limits, and no subscriptions required. The x402 challenge confirms the endpoint is live, returning a 402 Payment Required response with a valid payment challenge specifying maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields are returned beyond the URL path suggesting SSN data for employee 159. The nature of the data (SSN) raises significant regulatory and ethical concerns — SSNs are highly sensitive personally identifiable information (PII) subject to strict legal protections in the United States.

Quality
The endpoint is live (valid 402 challenge captured), but documentation is essentially nonexistent — all doc pages return only 'Connect wallet'. There is no OpenAPI schema, no request/response examples, and the endpoint exposes highly sensitive PII (SSN) with no visible compliance or authorization framework documented.
Warnings
- —This endpoint purports to serve Social Security Numbers (SSNs), which are highly sensitive PII regulated under US federal and state laws. Use without proper authorization may violate law.
- —No documentation exists beyond the landing page — docs, API, pricing, and README pages all show only 'Connect wallet'.
- —No OpenAPI schema or request/response examples are available; the actual data returned is unknown.
- —The endpoint path is hardcoded to employee ID 159; it is unclear whether other employee IDs are supported or what the data source is.
- —No information about data provenance, accuracy, or legal basis for serving SSN data is provided.
