It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, all gated behind the x402 payment protocol. The endpoint accepts POST requests and returns JSON.\n\nPayment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20000 base units, which at 6 decimals for USDC equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nThe endpoint is live and returning a valid x402 402 challenge. However, the nature of the data returned — employee SSN — raises significant regulatory and ethical concerns. SSNs are highly sensitive personally identifiable information (PII) subject to strict legal protections in the United States. There is no documentation available beyond the landing page, and the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. The actual data source, legitimacy, and compliance posture of this endpoint are entirely unknown.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data","ssn-lookup","pay-per-request","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","employee data API","x402 SSN","micropayment data access"],"warnings":["CRITICAL: This endpoint claims to serve Social Security Numbers, which are highly regulated PII.
