It is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com, all settled via the x402 protocol using USDC on the Base network.\n\nThe endpoint is live and returns a standard x402 402 challenge when called without payment. The price is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is made via the x402 \"exact\" scheme to the specified wallet address. The endpoint accepts POST requests and returns JSON. No API keys or rate limits are advertised; access is gated purely by micropayment.\n\nThe provider site lists many other endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all at the same $0.02 price point. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The nature of the data returned (employee SSN) raises significant regulatory and privacy concerns (PII, potential FCRA/GLBA implications).","tags":[],"capabilities":["x402-payment","usdc-base-network","employee-data-lookup","ssn-retrieval","pay-per-call","no-api-key"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII data endpoint","x402 employee data","micropayment SSN API","Base USDC data API"],"warnings":["Endpoint returns employee SSN data — highly sensitive PII.
