The endpoint accepts POST requests and is settled in USDC on the Base network. The x402 challenge confirms the endpoint is live and requires a maximum payment of 20,000 base units of USDC (0.02 USD, i.e., two cents per request).\n\nThe provider site lowpaymentfee.com hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint listed here is notably different from the other catalog entries: it exposes what appears to be personally identifiable information (an employee's SSN). No documentation, input schema, or sample responses are available beyond the x402 challenge and the landing page. The docs, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content.\n\nBecause this endpoint purports to serve Social Security Numbers — highly sensitive PII regulated under numerous privacy and data-protection laws — extreme caution is warranted. There is no documentation explaining the data source, authorization model, or legal basis for serving this data. Buyers should perform thorough due diligence before calling this endpoint.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","pay-per-call","no-api-key"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","Base USDC micropayment API","lowpaymentfee SSN"],"warnings":["This endpoint serves Social Security Numbers (PII) — accessing or distributing SSNs is heavily regulated under US federal and state law (e.g., GLBA, FCRA, state SSN protection statutes).
