It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utility categories — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific resource `/api/v1/employees/34` returns JSON and accepts POST requests. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, with a 300-second timeout window. No API keys, rate limits, or upfront commitments are required.\n\nDocumentation on the site is extremely thin — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI spec, no request/response schema, and no description of what fields the employee record contains. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data payload and use case remain unclear from available materials.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","employee-data","pay-per-request","no-api-key","json-response"],"categories":["data"],"synonyms":["employee API","employee record lookup","x402 API","pay-per-call data","USDC micropayment API","lowpaymentfee","Base USDC endpoint"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All documentation pages (docs, pricing, API, README) render only 'Connect wallet' with no content","The nature and source of 'employee' data is undocumented — unclear whether this is sample/demo data or a real dataset","No request body schema provided; unclear what POST body (if any) is expected"],"endpointUrl":"https://lowpaymentfee.com/api/v1/employees/34","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/34","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid 402 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what the employee data contains.
