The endpoint returns a 402 challenge requiring an X-PAYMENT header with an exact-scheme payment of 20,000 base units of USDC (0.02 USD per request, since USDC uses 6 decimals). No API keys or rate limits are required — access is gated purely by micropayment.\n\nThe provider lowpaymentfee.com hosts a broader catalog of x402 endpoints spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/employees/122` resource. The response MIME type is `application/json`. No OpenAPI schema, detailed documentation, or example responses were found in the crawl — the docs, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no substantive content.\n\nBecause the endpoint's actual response payload is undocumented and the purpose of an \"employees/122\" resource is unclear (it may be a demo or sample endpoint), consumers should treat this as a low-documentation offering. The x402 challenge is live and well-formed, confirming the endpoint is operational.","tags":[],"capabilities":["x402-payment","usdc-micropayment","base-network","json-response","employee-data","pay-per-call"],"categories":["data"],"synonyms":["employee API","x402 employee endpoint","micropayment API","USDC pay-per-call","lowpaymentfee","Base network API","402 payment API"],"warnings":["No documentation available — docs, pricing, and README pages render only 'Connect wallet' with no content.","The response schema for /api/v1/employees/122 is completely undocumented; consumers cannot know what fields to expect.","This appears to be a single-record endpoint (employee 122); it is unclear whether other employee IDs are available or if this is a demo resource.","No OpenAPI or AI plugin manifest found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/122","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/122","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and well-formed, confirming the endpoint works.
