The specific resource probed is `/api/v1/employees/99/ssn`, accepting POST requests and settling payments in USDC on the Base network.\n\nThe x402 challenge specifies a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the `exact` scheme to the specified payTo address, with a 300-second timeout. The endpoint returns JSON and requires no API keys or rate limits — access is granted per-request upon valid payment.\n\nThis endpoint is part of a broader platform at lowpaymentfee.com that offers numerous x402-gated APIs across categories including data analytics, AI/ML inference, finance, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint listed here deals with sensitive personally identifiable information (employee SSNs), which raises significant regulatory and ethical concerns. Documentation beyond the landing page is effectively empty (all subpages only show a \"Connect wallet\" prompt with no further content).","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","per-request-micropayment","json-response"],"categories":["data","pii"],"synonyms":["employee SSN API","social security number lookup","employee PII endpoint","x402 employee data","Base USDC micropayment API","lowpaymentfee employee API"],"warnings":["This endpoint serves Social Security Numbers (PII).
