Webhooks

Get a JSON POST to your endpoint when a monitor changes state. Signed with HMAC-SHA256 + your shared secret.

CLI

A small `host.tools` binary wraps the API. `host.tools dns lookup host.com --type=MX` works exactly as you expect.

SDKs

Official JavaScript / Python / Go / PHP / Rust packages. All thin — they just wrap /api/v1.
