## Workflow

### Step 1: Call the GrabGrab API

Use `curl` via the Bash tool to call the API:

```bash
curl -s -X POST "https://grabgrab.fun/api/download" \
  -H "Content-Type: application/json" \
  -d '{"url": "<VIDEO_URL>", "videoQuality": "<QUALITY>"}'
```

**Video quality options** (ask user if not specified, default to `1080`):
- `max` - Best available quality
- `2160` - 4K
- `1440` - 2K
- `1080` - Full HD (default)
- `720` - HD
- `480` - SD
- `360` - Low
- `144` - Minimum

**Download mode options** (default to `auto`):
- `auto` - Video with audio (default)
- `audio` - Audio only
- `mute` - Video without audio

### Step 2: Parse the API Response

The API returns JSON. Handle each response type:

**Direct download** (`type: "direct"`):
```json
{
  "success": true,
  "type": "direct",
  "url": "https://...",
  "filename": "video.mp4"
}
```
Action: Download the file using `curl -L -o <filename> "<url>"`.

**Picker** (`type: "picker"`) — multiple items found (e.g., Instagram carousel):
```json
{
  "success": true,
  "type": "picker",
  "items": [
    {"type": "video", "url": "https://..."},
    {"type": "photo", "url": "https://..."}
  ]
}
```
Action: Show the user the list of items and ask which ones to download, or download all videos.

**Error**:
```json
{
  "success": false,
  "error": "Error message here"
}
```
Action: Show the error message to the user.

### Step 3: Download the File

For direct downloads:
```bash
curl -L -o "<filename>" "<download_url>"
```

For tunnel/redirect URLs that need the proxy:
```bash
curl -L -o "<filename>" "https://grabgrab.fun/api/proxy?url=<encoded_download_url>"
```

IMPORTANT: If the direct URL download fails or returns HTML instead of a video file, retry using the proxy endpoint:
```bash
curl -L -o "<filename>" "https://grabgrab.fun/api/proxy?url=$(python3 -c 'import urllib.parse; print(urllib.parse.quote("<download_url>", safe=""))')"
```

### Step 4: Confirm to User

After download completes:
- Report the filename and file size
- Report the download location (current working directory or user-specified path)

## Important Notes

- The API has a rate limit of 30 requests per minute. If you get a 429 error, wait and retry.
- Always use `-L` flag with curl to follow redirects.
- If the user asks for audio only, set `downloadMode` to `"audio"`.
- If the user wants the best quality, set `videoQuality` to `"max"`.
- Default download location is the current working directory unless the user specifies otherwise.
- The API automatically detects the platform from the URL — no need to specify the platform manually.

## Examples

1. Call API: `curl -s -X POST "https://grabgrab.fun/api/download" -H "Content-Type: application/json" -d '{"url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ", "videoQuality": "1080"}'`
2. Parse response to get download URL and filename
3. Download: `curl -L -o "filename.mp4" "<url>"`
4. Report: "Downloaded filename.mp4 (15.2 MB) to current directory."

**User**: "Save the audio from this TikTok: https://www.tiktok.com/@user/video/123"

2. Parse and download the audio file
