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 190) behind an x402 paywall. It accepts POST requests and is settled in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per request.
The provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This specific endpoint is part of what appears to be an employee data API. The response MIME type is application/json.
Documentation beyond the landing page is extremely sparse — the /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 the response includes beyond the URL path suggesting it returns an SSN. The nature of the data (SSN) raises significant regulatory and privacy concerns (PII, potential FCRA/GLBA implications). Prospective users should exercise extreme caution and verify the legitimacy and compliance of this data source before use.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or data provenance. The sensitive nature of the data (SSN) with no compliance or legitimacy information significantly lowers confidence.
Warnings
- —This endpoint exposes Social Security Numbers — a highly regulated category of PII. Verify legal authorization (FCRA, GLBA, state privacy laws) before use.
- —No API documentation, OpenAPI schema, or response examples are available; all docs pages returned only 'Connect wallet'.
- —Data provenance and legitimacy are completely unknown — this could be synthetic/demo data or improperly sourced PII.
- —The endpoint path is hardcoded to employee ID 190; it is unclear whether other employee IDs are supported or how the broader API is structured.
