It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 0.02 USDC per request (20,000 base units at 6 decimals).\n\nThe broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nThis specific endpoint (/api/v1/employees/31) is not individually documented on the site's landing page, and no OpenAPI schema, request/response examples, or detailed documentation were found. The docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no additional content. As a result, the exact request format and response structure for this employee endpoint are unknown and must be discovered by the caller.","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 API","Base network API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/employees/31 path is not listed among the site's advertised APIs — it may be a demo or test endpoint","Docs, pricing, and API pages returned only 'Connect wallet' with no usable content","Request body format and response structure are completely unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/31","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/31","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 confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond the landing page listing.
