It is part of a broader platform (lowpaymentfee.com) that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance, and utility services, all settled on the Base network using USDC.\n\nThe specific endpoint `/api/v1/employees/35/salary` returns JSON and costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is made via the x402 protocol's `exact` scheme: the caller includes an `X-PAYMENT` header with a signed payment to the provider's address on Base. No API keys, rate limits, or subscriptions are required — each call is independently paid.\n\nThe broader lowpaymentfee.com platform advertises a uniform $0.02/request pricing across all endpoints. However, the specific endpoint being listed here (`/employees/35/salary`) is not prominently featured on the site's landing page, which focuses on analytics, AI, finance, and utility APIs. The purpose and schema of the salary response are not documented, so the exact fields returned are unknown. The endpoint is live and responding with a valid x402 challenge.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-request","json-response"],"categories":["data"],"synonyms":["employee salary API","payroll data endpoint","x402 salary lookup","pay-per-call employee data","Base USDC API","lowpaymentfee employee"],"warnings":["No documentation exists for the /api/v1/employees/35/salary endpoint specifically","Response schema is completely unknown — no output fields are documented","This endpoint is not listed among the provider's advertised APIs on the landing page","The endpoint appears to be for a hardcoded employee ID (35); unclear if other IDs are supported","Docs, API, pricing, and README pages all render only a 'Connect wallet' prompt with no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/35/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/35/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, confirming it works.
