It accepts POST requests and settles payments in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 per call.\n\nThe provider lowpaymentfee.com hosts a broad catalog of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. This particular endpoint falls under what appears to be an employee/HR data category, though the provider's landing page does not explicitly list it among its featured API groups.\n\nBecause the endpoint path references a hardcoded employee ID (174), it is unclear whether callers can query arbitrary employee IDs or whether this is a demo/sample resource. No OpenAPI schema, request body documentation, or response examples were found in the crawl. The docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no substantive content. Treat this endpoint as live but poorly documented.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-lookup","pay-per-request","no-api-key"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","HR salary lookup","x402 salary","micropayment employee data","USDC pay-per-call"],"warnings":["No API documentation found — docs, pricing, and API pages all return only a wallet-connect prompt with no content.","The endpoint path hardcodes employee ID 174; it is unclear if other IDs are supported or if this is a demo resource.","This endpoint is not listed among the provider's featured API categories on the landing page.","No request body schema or response schema is available; callers must guess at the expected input and output format."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/174/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/174/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 OpenAPI schema, no request/response documentation, no examples, and the docs pages are empty.
