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 platform (lowpaymentfee.com) that offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all at the same $0.02 per-call price point. Documentation beyond the landing page is essentially empty (all sub-pages just show \"Connect wallet\"), so there is no schema documentation for request body format or response structure. The specific data returned (employee SSN) raises significant regulatory and privacy concerns — SSNs are highly sensitive PII governed by laws such as the Privacy Act and various state data breach notification statutes.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data-lookup","ssn-retrieval","per-call-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 data API","Base USDC micropayment API","employee record API"],"warnings":["This endpoint purports to serve Social Security Numbers (SSNs), which are highly sensitive PII.
