It accepts POST requests and settles payments 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.\n\nThe provider lowpaymentfee.com hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance, crypto, and utility endpoints, all priced at $0.02 per call. This specific endpoint is part of an employee data resource. No API keys or rate limits are advertised; access is granted purely through the x402 payment protocol. The response MIME type is application/json.\n\nWARNING: This endpoint returns Social Security Numbers, which are highly sensitive personally identifiable information (PII) subject to strict legal regulations in the United States. Accessing, storing, or transmitting SSNs may trigger obligations under federal and state privacy laws (e.g., GLBA, state breach notification laws).
