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 authenticate.\n\nThe hosting provider, lowpaymentfee.com, offers a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, this specific endpoint (`/api/v1/employees/169/salary`) is not listed on the provider's public landing page among the advertised API categories. Its purpose — returning salary data for a hardcoded employee ID — is unclear and may be a demo or test endpoint rather than a production data source.\n\nNo OpenAPI schema, request/response examples, or detailed documentation were found during the crawl. The docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. Because of this, the exact request body format and response structure are unknown and must be discovered by the caller.","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"],"warnings":["Endpoint /api/v1/employees/169/salary is not listed on the provider's public API catalog — may be a test or demo endpoint","No documentation, OpenAPI spec, or response schema available","All doc/pricing/README pages returned only a wallet-connect prompt with no content","Request body format and response structure are completely unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/169/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/169/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 (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI schema, no request/response examples, and the endpoint is not listed among the provider's advertised APIs.
