It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\n\nThe provider, lowpaymentfee.com, hosts a broader catalog of pay-per-call APIs spanning data & analytics, AI/ML inference (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 advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments.\n\nThis specific endpoint (/api/v1/employees/59) is not documented in detail on the provider's landing page — it appears to be part of a broader employee or HR data resource. The x402 challenge was successfully captured (HTTP 402 with valid payment terms), confirming the endpoint is live. However, no OpenAPI schema, request/response examples, or detailed documentation were found for this particular resource, so the exact shape of the returned employee data is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-api","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee API","HR data endpoint","personnel record API","x402 employee data","pay-per-request data API","lowpaymentfee API","Base USDC API"],"warnings":["No documentation or schema found for /api/v1/employees/59 — request body and response shape are unknown","The /employees/59 path is not listed on the provider's landing page catalog, so its purpose and data content are unclear","Docs, API, pricing, and README pages all returned only 'Connect wallet' with no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/59","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/59","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI schema, no request/response examples, and no documentation for this specific /employees/59 endpoint.
