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 x402-gated APIs spanning data analytics, AI/ML inference, finance, and utility services, all priced at $0.02 per request. No API keys or rate limits are advertised; access is granted purely through x402 payment headers. Documentation pages beyond the landing page returned only a \"Connect wallet\" prompt with no additional technical detail.\n\nThis specific endpoint appears to serve sensitive personally identifiable information (an employee's SSN). The legitimacy and legal compliance of such an endpoint is unclear. There is no documentation explaining the data source, authorization model, or compliance framework. Prospective consumers should exercise extreme caution.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-request-micropayment","json-response"],"categories":["data","pii"],"synonyms":["social security number API","employee SSN lookup","PII endpoint","x402 employee data","Base USDC micropayment API"],"warnings":["Endpoint claims to serve Social Security Number data — this is highly sensitive PII.
