Overview

Install the Mynth CLI, log in with a browser approval, and generate images, manage keys, webhooks and destinations, and read these docs from the terminal.

The Mynth CLI works from a terminal or an agent's shell. It generates and analyzes images, reads tasks, and manages API keys, webhooks, and destinations. With --json, its output is stable enough to parse, and its exit codes tell scripts what went wrong.

Install

Node.js 20 or newer. Install globally for the mynth binary:

npm install -g @mynthio/cli
mynth --help

Or run any command without installing, as the examples in these docs do:

npx @mynthio/cli --help

Log in

npx @mynthio/cli auth login

The CLI prints a one-time code and opens your browser to approve it. It then creates an API key and stores it on this machine. Logging in covers where the key lives and which credential each command sends.

Generate an image

npx @mynthio/cli image generate \
  -m black-forest-labs/flux.2-pro \
  -p "A lighthouse at dusk, film grain"

The command waits and prints the image URL. Add -o ./images to save the file, or --json for machine-readable output.

Without an account

docs and models list work without logging in:

npx @mynthio/cli docs get getting-started
npx @mynthio/cli models list --type image

Next steps

Logging in: the stored key, and which credential is sent.
Commands: every command, its flags, and exit codes.
