Pay-per-call HR reviews endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides access to an HR reviews resource (specifically review ID 20) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/hr/reviews/20` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed payment proof for up to 20,000 base units of USDC (i.e., $0.02, since USDC uses 6 decimals). No API keys, accounts, or rate limits are advertised — access is gated purely by micropayment.
The platform's landing page lists endpoints across categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure) but does not provide detailed documentation, request/response schemas, or example payloads for any individual endpoint. The HR reviews endpoint is not listed on the homepage, making its exact data source and response format unclear. The x402 challenge confirms the endpoint is live and accepting payment challenges.
