The Sly CLI is a thin terminal shell over the Node SDK. Use it for ops, scripting, CI/CD, and anywhere you’d reach for curl.

​
Install

npm install -g @sly_ai/cli
# or
pnpm add -g @sly_ai/cli
Verify: 
sly --version

​
Authenticate

Environment variables: 
export SLY_API_KEY=pk_test_...   # or pk_live_*
# Optional: explicit URL override
export SLY_API_URL=https://api.getsly.ai
Your key prefix (pk_test_ vs pk_live_) auto-selects the correct base URL.
