Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint follows the x402 protocol: callers receive a 402 Payment Required challenge with payment details, then submit an X-PAYMENT header to complete the transaction and receive the response.\n\nThe hosting site lowpaymentfee.com offers a broad 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 commitments. This particular endpoint (/api/v1/employees/16/salary) is not listed on the site's public catalog, so its exact response schema and data source are unknown. The endpoint is live and returns a valid x402 challenge.\n\nBecause there is no OpenAPI schema, no documentation beyond the 402 challenge, and no example responses available, the actual structure and content of the salary data returned is uncertain. Callers should be prepared for a JSON response (mimeType is application/json) but will need to discover the exact fields empirically.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-call","employee-data","salary-lookup","json-response","no-api-key"],"categories":["data"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 employee data","pay-per-request salary","USDC API payment","Base network API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","Endpoint /api/v1/employees/16/salary is not listed on the provider's public API catalog — may be a demo or test endpoint","Response structure is completely unknown; no example responses available","Employee salary data may be synthetic/demo data — no indication of real data source"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/16/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/16/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 and returns a valid x402 challenge, but there is no OpenAPI schema, no documentation, no example request/response, and the endpoint is not listed in the provider's public catalog.
