Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and provides instant access — callers simply attach an x402 payment header to authorize each call.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request. However, the specific endpoint being listed here (`/api/v1/employees/90/salary`) is not prominently documented on the provider's landing page, which focuses on analytics, AI, finance, and utility endpoints. No OpenAPI schema, request body format, or response examples are provided in the available documentation.\n\nThe endpoint is live and returns a valid x402 challenge (HTTP 402) with version 1 of the protocol. The payment is routed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base, using the USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The maximum timeout for payment settlement is 300 seconds.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-call","no-api-key"],"categories":["data"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 employee data","USDC pay-per-call API","lowpaymentfee salary"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/employees/90/salary path is not listed among the provider's advertised APIs — it may be a demo or test endpoint","No request body schema or response examples are available; actual data format is unknown","Docs, pricing, API, and README pages all returned only 'Connect wallet' with no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/90/salary","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/90/salary","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 challenge, but there is no OpenAPI schema, no documented request/response format, and the specific employee salary endpoint is not listed on the provider's own landing page.
