# EchoTik TikTok Video Download

This skill guides you on how to resolve a TikTok video URL into direct download and playback links, helping sellers save influencer/promotional video assets for offline analysis or reuse.

## Core Concepts

This tool takes a single TikTok video URL and resolves it to direct media addresses: a no-watermark download URL (preferred for clean assets), a watermarked download URL, a playback URL, and cover images (static and dynamic). This is useful when a seller wants to archive a high-performing promotional video found via the product video tool, or reuse a creator's clip without re-recording.

**Required input**: A `url` is mandatory. Two URL formats are accepted:
- Short link: `https://vt.tiktok.com/xxxxxx`
- Full link: `https://www.tiktok.com/@user/video/1234567890`

**Conditional download URLs**: Not every video returns a downloadable address. `noWatermarkDownloadUrl` and `downloadUrl` are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only `playUrl` plus cover images come back. Always check presence before presenting a download link, and fall back to `playUrl` for playback when the download fields are missing.

**URL freshness**: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.

## Parameter Guide

| Parameter | Type | Required | Description | Default |
|-----------|------|----------|-------------|---------|
| url | string | Yes | TikTok video URL (short link `vt.tiktok.com/xxx` or full link `tiktok.com/@user/video/xxx`). Max length 1000 | - |

## How to Call

- **API Endpoint**: `POST /echotik/getVideoDownloadUrl` (see `references/api.md` for full parameters/response/error codes)
- **Python Script**: `python scripts/echotik_get_video_download_url.py '<JSON parameters>' [--inline]`
- **Cost constraint**: This tool consumes credits; the same parameter combination in the same session is called only once by default, with 24h local caching in the script. On failure/empty results, do not automatically retry with different keywords, pagination, or filter changes; inform the user before making additional queries.

**Output strategy (default script behavior)**:
- **Always** write the full response to `<cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-echotik-get-video-download-url-<timestamp>.json` (`<cwd>` is the working directory at script execution time, i.e., the current project directory in Claude Code; `<session>` is taken from the `SESSION_ID` environment variable, auto-grouped by user task; **do not write to /tmp**, error if the current directory is not writable)
- Response body <= 8 KB: print the full JSON to stdout after writing to disk
- Response body > 8 KB: stdout only outputs a summary (top-level fields, common counts like `total`/`costToken`, length of the largest list field + first 3 samples)
- Add `--inline` to force full output to stdout (still writes to disk)

**Data reading tip**: Check the summary first to see if sufficient; for specific fields, prefer using `jq` or `ConvertFrom-Json` to extract from the saved JSON file on demand, avoiding loading the entire JSON into context.

## Usage Examples

**1. Resolve a full TikTok video link**
```json
{
  "url": "https://www.tiktok.com/@user/video/1234567890"
}
```

**2. Resolve a TikTok short link**
```json
{
  "url": "https://vt.tiktok.com/Z123abc/"
}
```

## Display Rules

1. **Present the no-watermark link first**: When `noWatermarkDownloadUrl` is present, surface it as the primary download option, since clean assets are usually what sellers want
2. **Offer the watermarked variant**: Also list `downloadUrl` (watermarked) when present, in case the user wants the original branding
3. **Handle missing download URLs**: When both `noWatermarkDownloadUrl` and `downloadUrl` are absent (common for some videos), do not fabricate a download link -- tell the user the video has no direct download address and offer `playUrl` for playback/preview instead
4. **Provide playback + cover**: Mention `playUrl` for quick preview and `coverUrl` / `dynamicCoverUrl` for thumbnails
5. **Freshness caveat**: Remind the user that the resolved URLs may expire and should be downloaded promptly
6. **Present data only**: Show the resolved addresses clearly without subjective advice on how to use the video
7. **Error handling**: When resolution fails, explain the reason based on `errcode`/`errmsg` -- `400` means a missing/invalid `url`, `10000` means the link is not a valid/accessible TikTok video; suggest checking the URL format

## User Expression & Scenario Quick Reference

### Applicable Scenarios

| User Says | Scenario |
|-----------|----------|
| "Download this TikTok video" / "Save this TikTok clip" | Resolve a video URL into download links |
| "Get the no-watermark version of this TikTok video" | Prioritize `noWatermarkDownloadUrl` |
| "I want to save this influencer's promo video" | Resolve and archive a creator's video |
| "Give me a playable link for this TikTok video" | Return `playUrl` |
| "Get the cover/thumbnail of this TikTok video" | Return `coverUrl` / `dynamicCoverUrl` |

### Not Applicable Scenarios

- Listing promotional videos associated with a TikTok **product** (use the product video skill instead -- it needs a `productId`, not a video URL)
- Searching for TikTok products (use the product search skill)
- TikTok new product rankings (use the new product rank skill)
- TikTok live-stream data
- Video editing or content creation advice
- Non-TikTok platform video downloads

### Boundary Judgment

When users mention "TikTok video", determine whether they already have a **specific video URL** they want to download (this skill) or want to **discover videos linked to a product** (the product video skill). If the user provides a `tiktok.com` or `vt.tiktok.com` link and asks to save/download/extract it, this skill applies. If they mention a product ID and ask "what videos promote this product", use the product video skill instead.
