The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 \"exact\" scheme. The maximum amount required per call is 20,000 base units, which at 6 decimals for USDC equals $0.02 per request.\n\nThe broader lowpaymentfee.com platform advertises a variety of x402-gated 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 at the same $0.02/request price point. The platform emphasizes no API keys, no rate limits, and instant access.\n\nHowever, the specific endpoint being listed here (`/api/v1/employees/129`) is not mentioned on the provider's landing page among the advertised API categories. Its purpose appears to be returning data about a specific employee resource, but no documentation, schema, or example responses are available. The docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content. Without further documentation, the exact shape of the response and the nature of the employee data remain unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-api","per-request-billing","no-api-key"],"categories":["data"],"synonyms":["employee API","employee record","staff data","personnel endpoint","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee"],"warnings":["The /api/v1/employees/129 endpoint is not listed among the provider's advertised APIs — it may be a demo, test, or undocumented resource.","No documentation, response schema, or example responses are available for this endpoint.","All doc/pricing/API pages returned only a 'Connect wallet' prompt with no substantive content.","The nature and sensitivity of 'employee' data is unknown — could involve PII."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/129","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/129","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 this specific employee endpoint is not documented anywhere on the provider's site.
