The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) 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 offers multiple API categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities, all priced uniformly at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/employees/138`) is not documented on the provider's landing page among the advertised API categories. It appears to be a resource-specific endpoint returning data for a single employee record.\n\nBecause there is no OpenAPI schema, no response examples, and no documentation beyond the x402 challenge and the site's generic landing page, the exact shape of the response and the nature of the employee data returned are unknown. The endpoint is confirmed live (returns a proper 402 challenge), but callers should be aware that the data content and schema are undocumented.","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","x402 employee endpoint","pay-per-request data API","USDC micropayment API","lowpaymentfee employee","Base network API"],"warnings":["The /api/v1/employees/138 endpoint is not listed among the provider's advertised APIs on the landing page","No OpenAPI schema or response documentation available","Docs, pricing, and README pages are empty stubs ('Connect wallet' only)","Response schema and data content are completely unknown — callers cannot predict what fields are returned","The term 'employees' may imply personal data; verify compliance with applicable data protection regulations"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/138","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/138","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 402 challenge, confirming it works.
