It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, and utility categories. The endpoint settles payments on the Base network using USDC (contract 0x8335…2913) through the x402 exact-payment scheme.\n\nThe maximum amount required per call is 20,000 base units of USDC. Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the provider's advertised flat pricing of $0.02/request across all endpoints. No API keys or rate limits are advertised; access is granted immediately upon valid x402 payment. The payment timeout is 300 seconds.\n\nDocumentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the salary response contains or what input the POST body expects. The endpoint is live (returns a proper 402 challenge), but the actual data returned after payment is 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 salary","pay-per-call salary","employee compensation API","USDC micropayment API"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all render only a wallet-connect prompt with no content.","No OpenAPI or request/response schema provided; input body format and response fields are unknown.","Endpoint path is hardcoded to employee ID 74; unclear if other employee IDs are supported or how to discover them.","The nature and source of the 'salary' data is unspecified — could be mock/demo data."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/74/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/74/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 with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and the actual data returned is completely unknown.
