It is part of a broader suite of pay-per-request APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, and utility categories. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint `/api/v1/employees/199/salary` costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled via the x402 `X-PAYMENT` header with the \"exact\" scheme. The platform advertises no API keys, no rate limits, and instant access — you simply attach a valid x402 payment header to each call.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary endpoint returns or what input it expects beyond the HTTP POST method. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data payload and its structure are unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-request","no-api-key"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 API","pay-per-call API","USDC micropayment API","lowpaymentfee"],"warnings":["No API documentation available — all doc pages return only a wallet connect prompt","No request body schema or response schema provided; data structure is entirely unknown","The endpoint path suggests demo/sample data (employee ID 199) rather than a production data source","No terms of service, privacy policy, or SLA information found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/199/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/199/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 exists and accepts payments.
