The specific resource `/api/v1/employees/32` returns JSON data for employee ID 32 when called with a POST request and a valid X-PAYMENT header containing a USDC payment on the Base network.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. The x402 challenge confirms the price: maxAmountRequired of 20,000 base units of USDC (6 decimals) equals $0.02. Payment is made to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on the Base L2 network, with a 300-second timeout.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the employee record contains. The endpoint is confirmed live (402 challenge returned), but the actual data shape and content remain unknown.","tags":[],"capabilities":["x402-payment","usdc-base","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","lowpaymentfee API","USDC micropayment API","Base network API"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response fields","The actual content/shape of employee records is completely unknown","No information on data source, freshness, or accuracy of employee data","The endpoint path references a specific employee ID (32); it is unclear whether other IDs are supported or how to discover them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/32","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/32","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base).
