Field notes
r4ck maps natural-language infrastructure requests to structured filters and presents the result as a human-readable listing or machine-oriented output. The homepage shows provider, region, CPU, memory, storage, transfer, and billing details, with prices in both provider currency and estimated monthly USD. It also exposes example commands for curl, the r4ck CLI, and MCP, while noting that bulk use requires a key or an x402 payment path.
