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 EchoTik 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	-

调用方式

API 端点：
```
POST /echotik/getVideoDownloadUrl
```
（完整参数/响应/错误码见
```
references/api.md
```
）

Python 脚本：

python scripts/echotik_get_video_download_url.py '<JSON 参数>' [--inline]

成本约束：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。

输出策略（脚本默认行为）：

始终将完整响应写入
```
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-echotik-get-video-download-url-<timestamp>.json
```
（
```
<cwd>
```
为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；
```
<session>
```
取自环境变量
```
SESSION_ID
```
，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错）
响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如
```
total
```
/
```
costToken
```
、最大列表字段的长度 + 前 3 条样本）
加
```
--inline
```
强制全量打印到 stdout（同样落盘）

读数据建议：先看摘要判断是否足够；需要具体字段时优先用

jq

或

ConvertFrom-Json

从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。

解决认证和积分问题

发生以下异常情况时，采用 references/onboarding.md 引导解决问题：

异常情况

未配置API Key：环境变量未配置
```
LINKFOX_AGENT_API_KEY
```
，也未配置
```
LINKFOXAGENT_API_KEY
```
。
响应401或402状态码
响应提示积分或余额不足：消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。

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

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
Offer the watermarked variant: Also list
```
downloadUrl
```
(watermarked) when present, in case the user wants the original branding
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
Provide playback + cover: Mention
```
playUrl
```
for quick preview and
```
coverUrl
```
/
```
dynamicCoverUrl
```
for thumbnails
Freshness caveat: Remind the user that the resolved URLs may expire and should be downloaded promptly
Present data only: Show the resolved addresses clearly without subjective advice on how to use the video
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
```
linkfox-echotik-product-video
```
instead — it needs a
```
productId
```
, not a video URL)
Searching for TikTok products (use
```
linkfox-echotik-product-search
```
)
TikTok new product rankings (use
```
linkfox-echotik-new-product-rank
```
)
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

linkfox-echotik-product-video

instead.

积分消耗规则
