The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are made inline via the x402 protocol on the Base L2 network.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee endpoint returns or what input it expects. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data content and schema remain unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","paid data API","x402 employee endpoint","lowpaymentfee API","USDC micropayment API","Base network API"],"warnings":["No documentation available — all doc pages render only 'Connect wallet'","No OpenAPI or JSON schema describing request parameters or response fields","Unknown what employee data fields are returned","The specific endpoint /api/v1/employees/161 is not listed on the provider's homepage; it may be a demo or test record"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/161","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/161","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base).
