It is part of a broader platform offering various pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services, all gated behind the x402 payment protocol on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers must include an X-PAYMENT header with a valid payment proof. The maximum amount required is 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 USD (USDC uses 6 decimals). The payment timeout is 300 seconds. No API keys or rate limits are advertised; access is granted purely through per-request micropayment.\n\nImportant caveat: this endpoint purports to serve sensitive personally identifiable information (SSNs). The legitimacy, legality, and data source behind this endpoint are entirely unclear. There is no documentation, privacy policy, or terms of service visible on the site. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. Consumers should exercise extreme caution before interacting with this endpoint, as accessing or distributing SSN data may violate privacy laws in many jurisdictions.","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","micropayment SSN","Base USDC API"],"warnings":["Endpoint claims to serve Social Security Numbers (SSNs), which is highly sensitive PII regulated under numerous privacy laws (e.g., CCPA, GLBA, state breach notification laws).
