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 suite of pay-per-call APIs offered by lowpaymentfee.com, spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities. All endpoints on the platform share the same $0.02/request pricing model and x402 payment protocol on Base. However, the specific endpoint being listed here (/api/v1/employees/66/salary) is not documented on the provider's landing page among the advertised API categories, which raises questions about its intended use case and the shape of its response.\n\nNo OpenAPI schema, request/response examples, or detailed documentation were found for this endpoint. The docs, API, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no substantive content. The endpoint is confirmed live (returns a proper 402 x402 challenge), but the lack of documentation means callers must discover the response format empirically.","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 paid API","USDC micropayment API","lowpaymentfee","Base network API"],"warnings":["No OpenAPI or JSON schema available for request or response bodies","This specific endpoint (/api/v1/employees/66/salary) is not listed among the provider's advertised APIs on the landing page","All documentation pages (docs, API, pricing, README) returned only 'Connect wallet' with no content","Response format must be discovered empirically; no examples exist"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/66/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/66/salary","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it accepts payments on Base in USDC at $0.02/request.
