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 39) 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 is live and returning a proper 402 challenge.
This endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call. However, this specific endpoint deals with sensitive personally identifiable information (employee SSN), which raises significant regulatory and ethical concerns. Users should exercise extreme caution and ensure compliance with applicable data protection laws before accessing this endpoint.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation beyond a landing page, no example request/response bodies, and the endpoint exposes highly sensitive PII (SSN) with no visible compliance or authorization framework. The docs, pricing, and README pages all render only a 'Connect wallet' prompt with no substantive content.
Warnings
