Retrieve employee SSN data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to employee Social Security Number (SSN) data behind an x402 paywall. The specific resource `/api/v1/employees/134/ssn` returns SSN information for employee ID 134 when a valid x402 payment header is included with the POST request. Payment is settled in USDC on the Base network.
The endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base, with a timeout of 300 seconds.
No API keys or rate limits are advertised. The platform emphasizes a simple pay-per-use model with no minimums or commitments. Documentation pages beyond the landing page returned only a "Connect wallet" prompt with no additional technical detail, so the exact response schema and input parameters beyond the employee ID in the URL path are unknown.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, no examples, and all docs pages returned only a wallet-connect prompt. The endpoint deals with highly sensitive PII (SSNs) with no visible compliance or authorization documentation.
Warnings
- —This endpoint exposes Social Security Numbers — extremely sensitive PII. Verify legal compliance (e.g., FCRA, state privacy laws) before use.
- —No response schema or example is available; the actual data returned is unknown.
- —Documentation pages (/docs, /api, /pricing, /README) all returned only 'Connect wallet' with no technical content.
- —No authentication or authorization mechanism beyond payment is documented — anyone who pays may receive SSN data, raising serious privacy and regulatory concerns.
- —The legitimacy and data source of the SSN information is unverified.
