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 17) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 "exact" scheme.
The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The endpoint was live at probe time, returning a well-formed 402 challenge with a 300-second payment timeout.
This endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, and infrastructure utilities — all priced at $0.02 per call. However, the specific endpoint being listed here deals with sensitive personally identifiable information (employee SSN), which raises significant regulatory and ethical concerns. No documentation beyond the landing page was available; the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation, no example requests or responses, and the endpoint deals with highly sensitive PII (SSN) with zero compliance or privacy documentation. The docs/pricing/README pages are all empty beyond a wallet connect prompt.
Warnings
- —This endpoint exposes Social Security Numbers (PII). No privacy policy, compliance certifications, or data handling documentation is provided.
- —No OpenAPI schema or response examples are available — the actual response format is unknown.
- —The endpoint path is hardcoded to employee ID 17; it is unclear whether other employee IDs are supported or what data is returned.
- —Documentation pages (/docs, /pricing, /README, /api) contain no substantive content.
- —Serving SSN data via a public pay-per-call API may violate US federal and state privacy regulations.
