The x402 challenge confirms the endpoint is live and accepts payment via the \"exact\" scheme on the Base network using USDC (contract 0x8335…2913). The maximum amount required per request is 20,000 base units of USDC, which at 6 decimals equals $0.02 per call.\n\nThe broader lowpaymentfee.com platform advertises a range of API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities — all priced at $0.02 per request. However, this specific endpoint (/api/v1/employees/27) is not listed on the homepage's catalog and its exact response schema is undocumented. The endpoint accepts HTTP POST requests and returns application/json. No OpenAPI spec, detailed documentation, or example responses were found during crawling; the docs, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no substantive content.\n\nBecause the endpoint path suggests a single employee record lookup and no input schema or output schema details are available beyond the MIME type, the actual data returned is unknown. Users should treat this as a lightly documented, pay-per-call data endpoint. The platform requires no API keys and advertises no rate limits, with payment handled entirely through the x402 protocol on Base.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","pay-per-request","no-api-key","json-response"],"categories":["data"],"synonyms":["employee lookup","employee record API","x402 API","pay-per-call API","Base USDC endpoint","lowpaymentfee","premium API access"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/employees/27 path is not listed in the provider's own API catalog on the homepage","Docs, pricing, and README pages returned no useful content beyond a wallet-connect prompt","Response format and fields are completely unknown — only MIME type application/json is confirmed","Purpose of 'employee' data is unclear; could be sample/demo data"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/27","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/27","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 OpenAPI spec, no documented input/output schema, no example responses, and the docs pages are empty.
