It is part of a broader platform offering dozens of pay-per-request API endpoints across data analytics, AI/ML, finance, and utility categories, all settled on the Base network using USDC.\n\nThe endpoint accepts POST requests and returns application/json responses. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment on Base. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises a flat $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments.\n\nThe specific endpoint path (`/api/v1/employees/142/salary`) suggests it returns salary data for employee record 142. However, no documentation exists describing the request body schema, response fields, or whether other employee IDs are supported. The docs, pricing, and API pages on the site all render only a \"Connect wallet\" prompt with no further content. Without an OpenAPI spec or example responses, the exact data returned is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-request","json-response"],"categories":["data"],"synonyms":["employee salary API","payroll data endpoint","x402 salary lookup","USDC micropayment API","Base network API","pay-per-call data","lowpaymentfee API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","Docs, pricing, and API pages render only 'Connect wallet' with no usable content","Request body format and response fields are completely unknown","The endpoint path references a hardcoded employee ID (142); unclear if other IDs are supported","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/142/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/142/salary","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the specific data returned by this employee salary endpoint is undocumented.
