The Opper CLI is the official opper command for the terminal. It gives you direct platform access to make calls, manage models, inspect traces, track usage, and generate images. It can also launch coding agents (Claude Code, Claude Desktop, OpenCode, Codex, Hermes, OpenClaw, pi) and route their inference through Opper.

​
Install

npm i -g @opperai/cli
Or run any command on demand without installing: 
npx @opperai/cli <command>
Requires Node.js ≥ 20.12.

​
Quick start

opper login              # OAuth device flow
opper whoami             # confirm the active account
opper launch claude      # launch Claude Code through Opper

​
What you can do

Command groupWhat it does
login / logout / whoamiOAuth device flow and account inspection.
askAsk a question grounded on the installed Opper skills. Useful for “how do I…” questions about the platform, SDKs, or the CLI itself.
callRun an Opper call from the terminal, with --model and --stream.
launch <agent> / agents list / agents uninstall <agent>Launch coding agents through Opper (Claude Code, Claude Desktop, OpenCode, Codex, Hermes, OpenClaw, pi). agents uninstall removes the Opper integration without uninstalling the agent itself.
editorsWire AI code editors (OpenCode) to use Opper as a provider.
skillsInstall, update, list, or uninstall bundled Opper skills.
models, traces, usageManage every Opper platform resource directly.
image generateGenerate images from a prompt.
configManage stored API keys and slots.
For full flags on any subcommand: opper <command> --help. Or run opper with no arguments for an interactive menu.

Launch coding agents through Opper

opper launch <agent> routes a coding agent through Opper. Every model call from the agent goes through your Opper account, so you get the same traces, cost tracking, and model routing.
AgentSlugHow Opper plugs in
Claude CodeclaudeANTHROPIC_BASE_URL / ANTHROPIC_AUTH_TOKEN env vars
Claude Desktopclaude-desktopwrites a third-party-inference (deploymentMode: "3p") profile into ~/Library/Application Support/Claude-3p/ (macOS) / %LOCALAPPDATA%\Claude-3p\ (Windows); quits and reopens the GUI app to apply
OpenCodeopencodeprovider block in ~/.config/opencode/opencode.json
Codexcodex[model_providers.opper] block in ~/.codex/config.toml
Hermeshermesisolated HERMES_HOME=~/.opper/hermes-home/ so your real ~/.hermes/ is never touched
OpenClawopenclawopper provider entry in ~/.openclaw/agents/main/agent/models.json; defaults to running gateway start (background daemon)
pipiopper provider entry in ~/.pi/agent/models.json
Anything after the agent name is forwarded to the agent’s CLI verbatim (Claude Desktop is GUI-only and does not accept extra arguments): 
opper launch claude -- --print "Hello"
To remove an agent’s Opper integration without uninstalling the agent itself: 
opper agents uninstall claude-desktop   # works for any registered adapter

​
Ask the CLI a question

opper ask "<question>" runs an Opper agent grounded on the locally-installed Opper skills. The answer streams to your terminal, then prints token and request counts. 
opper skills install                                          # one-time
opper ask "how do I make a call?"
opper ask --model anthropic/claude-opus-4-7 "compare the v2 and v3 APIs"
Use ask to get unstuck without leaving the terminal. The model has the same skill packs available as the agents you launch through opper launch.

​
Authentication

Auth state lives in ~/.opper/config.json as a list of slots, each holding an API key and base URL. Use --key <slot> on any command to pick which slot to use. Resolution at request time: OPPER_API_KEY env var > slot named by --key (or default). 
opper config add staging <api-key> --base-url https://...
opper call --key staging my-call "instructions" "input"
