The specific resource `/api/v1/employees/151` returns JSON data for employee ID 151 when a valid USDC micro-payment is submitted on the Base network. The endpoint is live and responds with a standard x402 challenge (HTTP 402) requiring payment of up to 20,000 base units of USDC (0.02 USD) per request.\n\nThe provider lowpaymentfee.com hosts a broader suite 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. Payments settle on the Base L2 network using USDC (contract 0x8335…2913).\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the employee record contains or what input parameters the POST method expects. The endpoint is confirmed live via the 402 challenge, but the actual data returned after payment is unknown from available materials.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","staff records","personnel data","HR API","employee lookup","paid API","x402 API","micro-payment API"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all show only 'Connect wallet' with no content","No OpenAPI or schema describing request body or response fields for the employees endpoint","The purpose and contents of the employee data record are undocumented and cannot be verified","The endpoint path suggests a demo/sample resource (employee ID 151) rather than a production dataset"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/151","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/151","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 x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
