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 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 priced uniformly at $0.02 per request with no API keys, no rate limits, and no minimum commitments. Payments are made inline via the x402 X-PAYMENT header on the Base L2 network.\n\nThis specific endpoint (/api/v1/employees/9) appears to be a sample or demonstration resource — it is not listed among the provider's advertised API categories on the landing page. Documentation pages (/docs, /pricing, /README) returned only a \"Connect wallet\" prompt with no substantive content, so the exact schema of the employee record returned is unknown. The endpoint is confirmed live (402 challenge captured successfully).","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-response","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee API","personnel data","HR data endpoint","x402 API","pay-per-request API","Base USDC API","lowpaymentfee"],"warnings":["This endpoint (/api/v1/employees/9) is not listed among the provider's advertised API categories — it may be a demo or test resource.","No documentation is available: /docs, /pricing, and /README all return only a 'Connect wallet' prompt with no content.","Response schema is completely unknown — no OpenAPI spec, no examples, no field descriptions.","The 'employees' resource name suggests potentially sensitive personnel data; verify compliance with applicable data-protection regulations before use."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/9","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/9","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it works.
