The specific resource `/api/v1/employees/3` returns JSON data for employee ID 3. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broader suite of APIs across data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per call. However, the specific endpoint being listed here is the employee data resource. The x402 challenge confirms the endpoint is live, accepts POST requests, and returns application/json responses. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content.\n\nBecause no OpenAPI schema, request/response examples, or detailed documentation are available for this endpoint, the exact shape of the request body and response payload is unknown. The endpoint appears to be a demonstration or sample resource (employee record by ID). Callers should expect a JSON object describing an employee, but the specific fields are not documented.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","rest-api","per-call-pricing","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","staff data endpoint","personnel record API","x402 paid API","USDC micropayment API","Base network API","pay-per-call data"],"warnings":["No OpenAPI or schema documentation available for this endpoint","All doc/pricing/README pages return only a 'Connect wallet' stub with no content","Request and response body formats are completely undocumented","The endpoint appears to be a sample/demo resource (employee ID 3) — production reliability is unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/3","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/3","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 confirms pricing, network, and asset details.
