It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — access is gated purely by the x402 micropayment.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, the specific endpoint being listed here (/api/v1/employees/173) is not explicitly documented on the site's landing page among the advertised API categories. Its purpose appears to be retrieving data for a specific employee resource, but the exact response schema and input parameters are not documented.\n\nThe probe confirms the endpoint is live, returning a proper 402 challenge with x402 version 1. The payment timeout is 300 seconds. Documentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no example requests or responses, and no description of what fields the employee record contains.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-call","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 employee endpoint","micropayment API","pay-per-request data","lowpaymentfee","Base USDC API"],"warnings":["The /api/v1/employees/173 endpoint is not listed among the advertised APIs on the provider's landing page — its purpose and data content are unclear.","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no usable content.","No OpenAPI spec or response schema is available; the structure of the returned employee data is unknown.","The endpoint may be a demo or placeholder rather than a production data source."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/173","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/173","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 spec, no documented request/response schema, no examples, and the specific /employees/173 path is not listed among the site's advertised APIs.
