It 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 broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This specific endpoint falls under what appears to be a sample or demonstration resource (employees/165). The site advertises instant access via the Base network with wallet-based authentication.\n\nDocumentation is extremely thin: the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available from the crawl. The endpoint is confirmed live — it returns a proper 402 x402 challenge — but the actual data returned after payment is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","personnel data","HR data endpoint","x402 API","pay-per-request API","lowpaymentfee","Base USDC API"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown.","The /employees/165 path is not listed among the provider's advertised API catalog on the landing page.","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content.","Actual response data after payment is unverified; endpoint purpose may be a demo or sample resource."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/165","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/165","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live with a valid 402 x402 challenge and clear pricing ($0.02 USDC on Base).
