The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network using the x402 \"exact\" scheme.\n\nThe x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. The provider's landing page confirms a flat $0.02/request pricing model across all their API endpoints, with no API keys, no rate limits, and instant access. The site also offers endpoints in categories like data analytics, AI/ML inference, finance, and infrastructure utilities — all at the same price point.\n\nDocumentation is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what data is actually returned or what input the POST body expects. The endpoint path suggests it returns a Social Security Number for employee ID 86, which raises significant data sensitivity and regulatory concerns.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-request-micropayment","json-response"],"categories":["data","identity"],"synonyms":["employee SSN API","social security number lookup","employee PII endpoint","x402 data API","Base USDC micropayment API"],"warnings":["Endpoint appears to serve Social Security Number data — handling SSN is subject to strict regulations (e.g., state privacy laws, IRS Publication 1075, GLBA).
