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 81) behind an x402 paywall. The endpoint 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 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 with no API keys, no rate limits, and no minimum commitments. However, this specific endpoint exposes personally identifiable information (an employee's SSN), which raises significant regulatory and ethical concerns. No documentation, request/response schema, or usage examples are available beyond the x402 challenge and the landing page listing.
The endpoint is live and returns a proper 402 challenge. Payment is made via the x402 exact scheme to wallet 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base. The response MIME type is application/json. No input body schema or output body schema beyond the MIME type is documented.

Quality
The endpoint is live and returns a valid x402 402 challenge, but there is no documentation, no request/response schema, no examples, and the endpoint exposes highly sensitive PII (SSN) with no visible compliance or authorization framework. The crawled docs/pricing/README pages returned only 'Connect wallet' with no substantive content.
Warnings
- —This endpoint exposes Social Security Numbers (PII). Accessing, storing, or transmitting SSNs is subject to strict legal regulations (e.g., FCRA, state privacy laws, GDPR). Verify compliance before use.
- —No request body schema or response body schema is documented — the actual data format is unknown.
- —No documentation beyond the landing page listing and x402 challenge. Docs, pricing, and README pages returned no useful content.
- —The legitimacy and authorization model for serving employee SSNs via a public paywall endpoint is unclear and potentially problematic.
- —It is unknown whether this is real employee data or synthetic/demo data.
