It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 0.02 USDC per request (20,000 base units at 6 decimals).\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that advertises multiple API categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. The platform emphasizes simplicity: no API keys, no rate limits, no commitments, and instant access. Payment is handled entirely through the x402 header mechanism on the Base L2 network.\n\nDocumentation is extremely sparse. The /docs, /pricing, /api, and /README pages all resolve to a minimal \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains or what POST body (if any) is expected. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data returned after payment is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","per-call-pricing","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","pay-per-call API","x402 API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all show only 'Connect wallet' with no content","No OpenAPI or schema describing request body or response fields for the employee endpoint","The specific endpoint path (/api/v1/employees/181) suggests a single hardcoded record; unclear if other IDs are available","Purpose and contents of the 'employee' data are completely undocumented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/181","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/181","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, confirming pricing and network details.
