The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 \"exact\" scheme, with a maximum cost of $0.02 per request (20,000 base units of USDC with 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint deals with sensitive personally identifiable information (employee SSN), which raises significant regulatory and ethical concerns. No documentation beyond the landing page is available; the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content.\n\nBecause the endpoint is live (returning a valid 402 challenge) but the nature of the data it exposes is highly sensitive, and because there is no documentation explaining the data source, authorization model, or compliance posture, consumers should exercise extreme caution before integrating this endpoint.","tags":[],"capabilities":["x402-payment","usdc-base","employee-ssn-lookup","pay-per-request","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 SSN","employee data API","sensitive data retrieval"],"warnings":["This endpoint exposes Social Security Numbers — highly regulated PII.
