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, input schema, or example responses are available beyond the x402 challenge and the landing page listing.\n\nThe endpoint is live and returns a proper 402 challenge. The payment address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 and the USDC asset contract is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base. The x402 version is 1 with a maximum timeout of 300 seconds.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","pay-per-call","json-response"],"categories":["data","pii"],"synonyms":["employee SSN API","social security number lookup","employee PII endpoint","x402 employee data","Base USDC micropayment API"],"warnings":["This endpoint exposes Social Security Numbers (PII).
