The specific resource `/api/v1/employees/4` returns JSON data for employee ID 4 when called with a valid x402 payment header. 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 broader suite 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, the specific `/api/v1/employees/{id}` endpoint 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 endpoint is live and returns a proper x402 challenge (HTTP 402) when called without payment. It accepts POST requests and returns application/json. No OpenAPI spec, 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.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","json-api","pay-per-call"],"categories":["data"],"synonyms":["employee API","staff data endpoint","personnel record API","x402 data API","lowpaymentfee API","pay-per-request employee data","Base USDC API"],"warnings":["The /api/v1/employees/{id} endpoint is not listed among the provider's advertised APIs on the landing page — its data source and reliability are unknown.","No documentation, OpenAPI spec, or example responses are available; docs/pricing/README pages render only a wallet-connect prompt.","Response schema for employee data is entirely undocumented — callers cannot know what fields to expect."],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/4","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/4","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI spec, no example responses, and the docs pages are empty.
