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 187) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per call. The site advertises no API keys, no rate limits, and instant access. However, documentation pages (/docs, /pricing, /README) returned only a "Connect wallet" prompt with no substantive content, so there is no schema documentation, request/response examples, or detailed description of what the SSN endpoint actually returns beyond its URL path.
This specific endpoint's purpose — exposing an employee's SSN — raises significant data-sensitivity and regulatory concerns. There is no documentation explaining the data source, authorization model, or compliance posture. Prospective consumers should exercise extreme caution and verify the legitimacy and legality of accessing this data before making any calls.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation for request/response schema, no examples, and the docs/pricing/README pages are empty. The endpoint exposes highly sensitive PII (SSN) with no visible compliance or authorization documentation, which is a major red flag.
Warnings
- —Endpoint exposes personally identifiable information (SSN) — verify legal and regulatory compliance before use.
- —No request or response schema documentation available; all docs pages returned only 'Connect wallet'.
- —No OpenAPI spec, no AI plugin manifest, no robots.txt or agents.txt found.
- —Data source and legitimacy of employee records are completely unknown.
- —This may be a demo or test endpoint — the fixed employee ID 187 in the URL suggests synthetic data, but this is unconfirmed.
