It is part of a broader platform offering various pay-per-request APIs across data analytics, AI/ML, finance, and infrastructure categories, all settled via the x402 protocol on the Base network using USDC.\n\nThe endpoint accepts POST requests and is gated by an x402 payment challenge. The price is $0.02 per request (20,000 base units of USDC, which has 6 decimals). Payment is made to the specified wallet address on Base, and the response is delivered as application/json. No API keys or rate limits are advertised — access is granted purely through per-call payment.\n\nThis is a sensitive endpoint that returns personally identifiable information (PII), specifically Social Security Numbers. The legitimacy and legal compliance of this data source is unclear from the available documentation. The provider's landing page lists many API categories but provides almost no documentation beyond the homepage listing. The docs, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","per-request-micropayment","employee-data-lookup","ssn-retrieval","base-network","usdc-settlement","json-response"],"categories":["data","pii"],"synonyms":["employee SSN lookup","social security number API","PII data endpoint","x402 employee data","micropayment data API","pay-per-request SSN"],"warnings":["This endpoint claims to return Social Security Numbers (PII).
