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), which at 6 decimals 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 payment timeout is 300 seconds.\n\nThis endpoint is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per call via x402. Documentation beyond the landing page is extremely sparse; the /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. No OpenAPI schema, request body schema, or response schema is available, so the exact request format and response structure are unknown.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","ssn-lookup","per-request-micropayment"],"categories":["data"],"synonyms":["employee SSN API","social security number lookup","employee record API","x402 data endpoint","paid data API","Base USDC micropayment API"],"warnings":["Endpoint returns sensitive PII (Social Security Numbers) — subject to strict regulatory requirements (e.g., FCRA, state privacy laws, GDPR-adjacent rules).","No documentation available: /docs, /pricing, /api, and /README all return only 'Connect wallet' with no content.","No request body schema or response schema is documented; callers must guess the format.","Endpoint path is hardcoded to employee ID 147 — unclear if other employee IDs are supported or how to discover them.","Serving SSN data behind only a $0.02 micropayment with no authentication or access control is a major red flag for data handling practices."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/147/ssn","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/employees/147/ssn","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no OpenAPI spec, and the endpoint path is hardcoded to a single employee ID.
