The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/25) is not mentioned on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear.\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 spec, no example request/response, and no description of what the employee record contains. Callers should expect a JSON object but will need to discover the schema empirically.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","pay-per-request","employee-data","json-api","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 API","pay-per-call data","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["The /api/v1/employees/25 endpoint is not listed among the provider's advertised APIs on the landing page — its purpose and data source are unverified.","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content.","No OpenAPI spec or response schema available; callers must discover the response format empirically.","The term 'employees' may imply personal data — callers should verify compliance with applicable data protection regulations."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/25","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/25","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no example responses, and the /employees/25 path is not listed among the provider's advertised APIs.
