Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and no upfront commitments — callers simply attach an x402 payment header to each request.\n\nThe provider, lowpaymentfee.com, hosts 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. This particular endpoint (`/api/v1/employees/46/salary`) is not listed on the provider's public landing page among the advertised API categories, which raises questions about its intended audience and whether it returns real or demo data. No OpenAPI schema, request/response examples, or detailed documentation were found during the crawl — the docs, pricing, and API pages all rendered only a \"Connect wallet\" prompt with no further content.\n\nThe endpoint is confirmed live: it returns a proper x402 version-1 challenge with a 402 status code, advertising USDC payment on Base to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3. The output schema indicates it accepts HTTP POST and is marked as discoverable. Without documentation or sample responses, the exact shape of the returned salary data is unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-salary-data","pay-per-call","no-api-key"],"categories":["data","finance"],"synonyms":["employee salary API","payroll data endpoint","salary lookup","x402 salary","pay-per-request salary","USDC API","Base network API","lowpaymentfee"],"warnings":["This specific endpoint (/api/v1/employees/46/salary) is not listed on the provider's public landing page — its purpose and data authenticity are unclear.","No documentation, request schema, or response schema is available; the shape of returned data is unknown.","Docs, pricing, API, and README pages all render only 'Connect wallet' with no usable content.","May return demo/synthetic data rather than real employee salary information."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/46/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/46/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 challenge, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation.
