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 (employee ID 55). It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. Payment is settled in USDC on the Base network.
The x402 challenge confirms the endpoint is live and accepts POST requests. The maxAmountRequired is 20000 base units of USDC (6 decimals), which equals $0.02 per request. The provider advertises a flat $0.02/request pricing model across all their endpoints, with no API keys, no rate limits, and instant access. The site also offers endpoints for analytics, AI/ML inference, finance data, and utility services, all at the same price point.
This specific endpoint raises significant concerns. It purports to return a US Social Security Number — highly sensitive personally identifiable information (PII) subject to strict legal regulations. There is no documentation explaining the data source, whether the data is real or synthetic, or what legal basis exists for its distribution. The endpoint path hardcodes employee ID 55, and it is unclear whether other employee IDs are supported or what the broader dataset looks like. No OpenAPI schema, response examples, or detailed documentation were found during the crawl — the docs, pricing, and API pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response format, no OpenAPI schema, no response examples, and the endpoint deals with highly sensitive PII (SSN) with no explanation of data provenance or legality. The docs pages returned no useful content.
Warnings
- —This endpoint claims to return Social Security Numbers — highly regulated PII. No documentation exists explaining whether the data is real or synthetic, or what legal basis supports its distribution.
- —No OpenAPI schema, response examples, or meaningful documentation found.
- —The endpoint path hardcodes employee ID 55; it is unclear if other IDs are supported.
- —All documentation pages (docs, pricing, API, README) returned only a 'Connect wallet' prompt with no substantive content.
- —Use of this endpoint with real PII may violate US federal and state privacy laws (e.g., GLBA, state SSN protection statutes).
