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/45` 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/45` appears to serve HR-related review data (likely a single review record identified by ID 45), though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepts POST requests, and requires a payment of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). Payment is made via the `exact` scheme with a 300-second timeout.
The broader lowpaymentfee.com platform advertises categories including Data & Analytics, AI & Machine Learning, Finance & Web3, and Infrastructure utilities. All endpoints share the same $0.02 pricing model. No OpenAPI spec, detailed documentation, or example responses were found during the crawl — the /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content.
