HR reviews data endpoint, pay-per-call via x402 on Base with USDC at $0.02/request.
What it does
This endpoint at `/api/v1/hr/reviews/4` is part of the lowpaymentfee.com platform, a collection of x402-protocol pay-per-request APIs spanning data analytics, AI/ML, finance, infrastructure, and more. The specific resource appears to serve HR review data (likely a single review record identified by ID 4), accessible via POST and paid per-call using USDC on the Base network.
The x402 challenge confirms the endpoint is live and accepts exact-scheme payments with a maximum amount of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals). This aligns with the site-wide advertised price of $0.02 per request. No API keys or rate limits are required — payment is the sole access control. The response MIME type is `application/json`.
Note that the endpoint path (`/api/v1/hr/reviews/4`) does not appear in the site's publicly listed API catalog, which focuses on analytics, AI, finance, and utility categories. There is no dedicated documentation, request/response schema, or example payload available for this specific HR reviews resource. The exact fields returned and the accepted POST body are unknown. The platform itself is minimal, with most pages behind a "Connect wallet" gate and no OpenAPI spec or detailed docs published.
