It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; callers simply attach an X-PAYMENT header with a valid x402 payment proof.\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. However, the specific endpoint being listed here (/api/v1/employees/89) is not documented on the provider's landing page among the advertised APIs. Its exact response schema and the nature of the employee data it returns are unknown; the only confirmed details come from the x402 challenge itself.\n\nThe endpoint is live and returns a well-formed x402 challenge (version 1, scheme \"exact\"). The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a maximum timeout of 300 seconds. Documentation on the site is essentially empty beyond the landing page catalog — the /docs, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no substantive content.","tags":[],"capabilities":["x402-payment","usdc-base","employee-data","pay-per-request","json-response"],"categories":["data"],"synonyms":["employee API","employee record","HR data endpoint","x402 employee","pay-per-call data","lowpaymentfee API","Base USDC API"],"warnings":["The /api/v1/employees/89 endpoint is not listed among the provider's advertised APIs on the landing page — it may be a test or demo endpoint.","No documentation exists for this endpoint: /docs, /pricing, and /README pages are empty.","Response schema is completely unknown — no outputSchema fields beyond the input method are provided.","The employee data returned may contain PII or sensitive HR information; verify compliance requirements before use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/89","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/89","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, but the specific /employees/89 path is not listed among the provider's advertised APIs.
