Pay-per-call HR reviews endpoint on Base via x402 — $0.02 per request in USDC.
What it does
This endpoint at `/api/v1/hr/reviews/13` is part of the lowpaymentfee.com platform, a collection of x402-gated APIs spanning data analytics, AI/ML, finance, infrastructure, and more. Each endpoint charges $0.02 per request, settled in USDC on the Base network with no API keys, rate limits, or subscriptions required.
The specific resource `/api/v1/hr/reviews/13` appears to serve HR review data (likely a single review record identified by ID 13), though it is not listed among the advertised API categories on the provider's landing page. The x402 challenge confirms the endpoint is live: it returns a 402 with an `exact` payment scheme requiring up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) on Base, payable to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The response MIME type is `application/json` and the expected HTTP method is POST.
No OpenAPI schema, detailed documentation, or example responses are available for this specific endpoint. The provider's site beyond the landing page requires a wallet connection, so deeper docs could not be crawled. Because the endpoint path (`/hr/reviews/13`) is not featured in the public API catalog, its exact data shape and purpose remain uncertain.
