The specific resource `/api/v1/employees/72` returns JSON data for employee ID 72 when a valid USDC micro-payment is submitted on the Base network. The endpoint accepts POST requests and requires an X-PAYMENT header containing the x402 payment proof.\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 data, and utility services — all priced at $0.02 per request. Payment is settled in USDC (contract 0x8335…2913) on Base L2, with no API keys, no rate limits, and no upfront commitments required. The x402 challenge advertises a maxAmountRequired of 20000 base units, which equals $0.02 USD (USDC uses 6 decimals).\n\nNote that while the landing page lists many endpoint categories, the specific `/api/v1/employees/{id}` path is not listed among them, and no documentation or schema for the employee data response was found. The docs, pricing, and API pages all returned only a \"Connect wallet\" prompt with no further content. As a result, the exact shape of the employee record returned is unknown and must be discovered by making a paid request.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-l2","employee-data","per-call-pricing","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","staff record lookup","employee data endpoint","x402 employee","pay-per-call data API","USDC micropayment API","Base network API"],"warnings":["No documentation available — docs, pricing, and API pages all return only 'Connect wallet' with no content.","The /api/v1/employees/{id} path is not listed among the provider's advertised endpoints, raising questions about its intended use.","No response schema or example data is available; the shape of the returned employee record is unknown.","No OpenAPI spec or ai-plugin manifest found."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/72","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/72","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 OpenAPI schema, no response examples, and no documentation beyond a wallet-connect prompt.
