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 payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) per request.\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 serves sensitive personally identifiable information (PII) — an employee's Social Security Number — which raises significant regulatory and ethical concerns. No documentation, request schema, or response schema is provided beyond the x402 challenge metadata.\n\nThe endpoint returns application/json content. No OpenAPI spec, detailed docs, or example responses were found in the crawl. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-ssn-lookup","pii-data-access","pay-per-request"],"categories":["data","pii"],"synonyms":["employee SSN API","social security number lookup","PII endpoint","x402 employee data","Base USDC micropayment API"],"warnings":["This endpoint exposes Social Security Numbers (PII).
