Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authorize each call.\n\nThe hosting site lowpaymentfee.com offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. This particular endpoint appears to serve employee salary data, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live and accepting payment challenges with a 300-second timeout.\n\nBecause there is no OpenAPI spec, no documented request/response schema, and the crawled docs/pricing/README pages returned only a \"Connect wallet\" stub, the actual data format and fields returned are unknown. The endpoint's purpose (employee salary lookup) is inferred solely from the URL path. Treat this as a lightly documented endpoint with verified liveness.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","salary-lookup","pay-per-call","no-api-key"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 employee data","USDC pay-per-call API","lowpaymentfee salary","Base network API"],"warnings":["No OpenAPI or request/response schema available — actual data format is unknown","All documentation pages (/docs, /api, /pricing, /README) returned only 'Connect wallet' with no content","Endpoint purpose (employee salary data) is inferred solely from URL path; no confirmation from docs","The specific employee ID (59) is hardcoded in the URL — unclear if other IDs are supported or how to discover them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/59/salary","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/59/salary","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 via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
