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 (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 priced uniformly at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are handled entirely through the x402 protocol on the Base L2 network.\n\nThis specific endpoint (/api/v1/employees/46) appears to be an employee record lookup. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. The exact fields returned in the employee JSON response are unknown and must be discovered by making a paid request.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-api","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 API","pay-per-request API","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available — response fields are unknown","Docs, pricing, and README pages return only 'Connect wallet' with no content","The specific purpose and data fields of /api/v1/employees/46 are undocumented","No example responses available; output must be discovered via paid request"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/46","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/46","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 captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documentation beyond a landing page, no example request/response, and the response format for the employee record is entirely unknown.
