It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\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. The platform advertises no API keys, no rate limits, and instant access. However, this specific endpoint (/api/v1/employees/192) is not listed on the provider's landing page among the advertised API categories, so its exact response schema and data source are unclear.\n\nThe x402 challenge was successfully captured (HTTP 402 with a valid accepts block), confirming the endpoint is live. Documentation pages (/docs, /pricing, /api, /README) all returned only a \"Connect wallet\" prompt with no substantive content, so there is no detailed schema or usage documentation available beyond what the challenge itself reveals.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-response","pay-per-call"],"categories":["data"],"synonyms":["employee API","employee record lookup","personnel data endpoint","x402 employee data","pay-per-call data API","lowpaymentfee API"],"warnings":["The /api/v1/employees/192 endpoint is not listed among the provider's advertised APIs on the landing page — its data source and purpose are unclear.","All documentation pages (/docs, /pricing, /api, /README) returned no substantive content, only a 'Connect wallet' prompt.","No response schema or example output is available; the actual data returned is unknown.","No OpenAPI spec or AI plugin manifest was found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/192","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/192","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 documentation, no response schema, no example responses, and this specific employees endpoint is not even listed on the provider's own landing page.
