# mmx Quickstart

Use mmx to generate text, images, video, speech, music, and search via the MiniMax AI platform.

## Install and Authenticate

```bash
# Install
npm install -g mmx-cli

# Authenticate with API key (persisted to ~/.mmx/credentials.json)
mmx auth login --api-key sk-xxxxx

# Or use environment variable (checked before stored credentials)
export MINIMAX_API_KEY=sk-xxxxx
```

Get API key: https://platform.minimax.io/subscribe/token-plan

## Agent Flags

Always use these flags in non-interactive (agent/CI) contexts:

| Flag | Purpose |
|---|---|
| `--non-interactive` | Fail fast on missing args instead of prompting |
| `--quiet` | Suppress spinners/progress; stdout is pure data |
| `--output json` | Machine-readable JSON output |
| `--async` | Return task ID immediately (video generation) |
| `--dry-run` | Preview the API request without executing |
| `--yes` | Skip confirmation prompts |

## Auth Precedence

Credentials are resolved in this order:
1. `--api-key` flag
2. `MINIMAX_API_KEY` env var
3. `~/.mmx/credentials.json` (stored OAuth/API key)
4. `api_key` in `~/.mmx/config.yaml`

## Config Precedence

CLI flags → environment variables → `~/.mmx/config.json` → defaults.

## Exit Codes

| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | General error |
| 2 | Usage error (invalid arguments) |
| 3 | Authentication error |
| 4 | Quota exceeded |
| 5 | Timeout |
| 10 | Content filter triggered |
| 130 | Interrupted (Ctrl+C) |

## mmx auth

```bash
# Login with API key
mmx auth login --api-key sk-xxxxx

# OAuth browser flow
mmx auth login

# Device-code flow (no browser)
mmx auth login --no-browser

# Check authentication status

```
