The specific resource `/api/v1/employees/183/salary` returns salary information for employee ID 183 in JSON format. Payment is handled inline using the x402 protocol on the Base network, settling in USDC (contract 0x8335…2913) at a cost of $0.02 per request.\n\nThe provider lowpaymentfee.com hosts a broader catalog of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities—all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. The employee salary endpoint is not listed on the provider's public landing page among the featured APIs, so its exact response schema and data source are undocumented. The x402 challenge confirms the endpoint is live and accepting payment-gated POST requests.\n\nBecause there is no OpenAPI spec, no request/response schema documentation, and no example payloads available, consumers should treat this as a lightly documented endpoint. The payment mechanics are well-defined (x402 v1, exact scheme, USDC on Base), but the business logic behind the salary data is opaque.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-call","json-response"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 paid API","USDC micropayment API","lowpaymentfee","employee compensation data"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/employees/183/salary path is not listed among the provider's publicly advertised APIs","No request body schema or response schema documented—consumers must discover the interface by trial","Data source and accuracy of employee salary information are unknown","Docs, API, pricing, and README pages all render only a 'Connect wallet' prompt with no substantive content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/183/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/183/salary","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint exists and accepts USDC payments on Base at $0.02/request.
