It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated behind x402 micropayments on the Base network.\n\nThe specific resource `/api/v1/employees/149` returns JSON data when a valid x402 payment header is supplied. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request. Payment is settled on-chain to the provider's wallet. No API keys, rate limits, or subscriptions are required — each call is independently paid.\n\nThe endpoint's purpose appears to be serving structured employee data, though the exact response schema is not documented in the crawled material. The broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing model across all its endpoints. Documentation pages (/docs, /pricing, /README) returned only a \"Connect wallet\" prompt with no substantive content, so details about request parameters, response fields, and data sources remain unknown.","tags":[],"capabilities":["x402-payment","per-request-micropayment","usdc-base","employee-data","json-response","no-api-key","no-rate-limit"],"categories":["data"],"synonyms":["employee API","staff record lookup","HR data endpoint","x402 micropayment API","pay-per-call data","lowpaymentfee employee","Base USDC API"],"warnings":["No response schema or example response available — actual data returned is unknown","Documentation pages (/docs, /pricing, /README) contain no content beyond a wallet-connect prompt","The nature and source of 'employee' data is undocumented — unclear if this is sample/demo data or a real dataset","No OpenAPI spec or machine-readable schema provided"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/149","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/149","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation of request parameters, response schema, or data source.
