The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 \"exact\" scheme.\n\nThe 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 valid 402 challenge.\n\nThis 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 (SSN), which raises significant regulatory and ethical concerns. Users should exercise extreme caution and ensure compliance with applicable privacy laws before accessing this data.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-request-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee record API","x402 data access","micropayment SSN"],"warnings":["This endpoint exposes Social Security Numbers — highly regulated PII.
