The specific resource `/api/v1/employees/128` returns JSON data for employee ID 128 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).\n\nThe platform advertises no API keys, no rate limits, and instant access. Documentation pages exist at /docs, /pricing, and /api but currently render only a \"Connect wallet\" prompt with no substantive content. The actual response schema for the employee endpoint is not documented, so the exact fields returned are unknown. The endpoint is live and returning a proper 402 challenge.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","staff data endpoint","HR data API","personnel API","x402 employee data","paid data endpoint"],"warnings":["No response schema documented — the exact fields returned for employee records are unknown","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no substantive content","The /api/v1/employees/128 endpoint is not listed on the provider's homepage among available APIs, raising questions about whether it is a demo or production resource","No input schema documented — unclear if POST body parameters are required or what they should contain"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/128","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/128","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing.
