It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) through the x402 \"exact\" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). No API keys or rate limits are advertised — access is granted purely through the x402 payment header.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that advertises multiple API categories including data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint probed (/api/v1/employees/135) is not listed among the advertised categories on the landing page, so its exact data schema and response fields are unknown. The platform's documentation, pricing, and API pages all appear to require a wallet connection and provide no additional detail in the crawled content.\n\nBecause there is no OpenAPI spec, no response schema, and no documentation beyond the landing page summary, the actual structure of the employee record returned is unclear. Agents should expect a JSON response but will need to inspect the payload to determine available fields.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee record API","employee lookup","staff data endpoint","personnel API","x402 micropayment API","pay-per-request data"],"warnings":["No OpenAPI or response schema available — response structure is unknown","The /api/v1/employees/135 path is not listed among the provider's advertised endpoints","Documentation, pricing, and API pages returned no useful content beyond 'Connect wallet'","The nature and source of the 'employee' data is undocumented; data accuracy and freshness are unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/135","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/135","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).
