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/37` 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, no rate limits, and no commitments required.
The specific resource `/api/v1/hr/reviews/37` appears to serve HR review data (likely a single review record identified by ID 37), though it is not listed among the advertised API categories on the site's landing page. The x402 challenge confirms the endpoint is live, accepting POST requests and requiring an exact payment of 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) on the Base network. The response MIME type is `application/json`.
Because this particular endpoint is not featured in the provider's public API catalog and no documentation, request/response schema, or example payloads are available, the exact data structure returned is unknown. The broader platform advertises categories like Data & Analytics, AI & ML, Finance & Web3, and Infrastructure utilities, all at the same $0.02 price point. The endpoint follows the x402 protocol (version 1) with a 300-second payment timeout.
