It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.\n\nThe endpoint charges a maximum of $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is handled inline via the x402 protocol: callers receive a 402 challenge containing the payment terms, then attach an X-PAYMENT header with a signed USDC transfer to complete the request. No API keys, subscriptions, or rate limits are advertised — access is entirely pay-as-you-go.\n\nDocumentation beyond the landing page is extremely thin. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific data returned by the salary endpoint (fields, format, whether it is real or demo data) is unknown from the available material.","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","x402 API","USDC micropayment API","Base network API","lowpaymentfee","pay-per-call data"],"warnings":["No OpenAPI spec or request/response schema available","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","The nature of the salary data (real, synthetic, demo) is unknown","The specific employee ID 198 is hardcoded in the endpoint path — unclear if other IDs are supported"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/198/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/198/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 spec, no request/response schema, no documentation, and no examples.
