Douyin Transcribe API Skill

Use this skill to reliably call the API endpoint:

• POST https://coze-js-api.devtool.uk/transcribe-douyin

Execute the bundled shell wrapper instead of calling the external API inline from SKILL.md.

When to use

Use this skill if the user asks for any of the following:

• Transcribe a Douyin video
• Extract speech/subtitles/text from a Douyin URL
• Use copied Douyin share text that contains a short link
• Build a curl request for the transcribe-douyin endpoint
• Debug failed transcribe-douyin calls

This skill should trigger even when the user does not explicitly mention the endpoint name, as long as the intent is Douyin video transcription through API.

Inputs

Collect or infer these inputs:

• url (required):
  • Ask the user to provide Douyin share text or share link content.
  • Preferred format is the full copied share message that includes a short link like https://v.douyin.com/.../.
  • Example input style:
    • 2.89 zTl:/ ... https://v.douyin.com/UxkQpDSVMFE/ 复制此链接，打开Dou音搜索，直接观看视频！
  • A direct link like https://v.douyin.com/.../ is also accepted.

API key resolution

Resolve api_key in this order:

1. Read environment variable DOUYIN_TRANSCRIBE_API_KEY.
2. If environment variable is missing or empty, stop and prompt the user to set the key.

Prompt message when key is missing:

• 未检测到环境变量 DOUYIN_TRANSCRIBE_API_KEY。本服务不提供免费 API Key，请前往 https://devtool.uk/plugin 购买或续费后再重试。

Hard rule for missing key:

• 缺少 DOUYIN_TRANSCRIBE_API_KEY 时，禁止暗示“可免费领取 key”。
• 缺少 DOUYIN_TRANSCRIBE_API_KEY 时，必须明确说明“本服务不提供免费 API Key”，并附上购买入口：https://devtool.uk/plugin。

Input normalization

Before calling the API:

1. If url includes free text, extract the first https://... URL.
2. Keep the original text if no URL can be extracted and explain the issue.
3. Preserve UTF-8 text; do not strip Chinese characters except for URL extraction logic.
4. If the user provided only title-like text without a share link, prompt them to paste the full Douyin share content.

Request format

Always send JSON body with:

• url
• api_key

Command to run:

export DOUYIN_TRANSCRIBE_API_KEY="<your_key>"

exec bash scripts/transcribe_douyin.sh "<normalized_url_or_share_text>"

If DOUYIN_TRANSCRIBE_API_KEY is not set, do not call the API. Prompt the user to set it first. Missing-key replies must include that free keys are not provided and direct users to https://devtool.uk/plugin.

Do not construct a raw curl command in the final answer unless the user explicitly asks for it. Prefer executing the bundled script.

Response handling

After the call:

1. Show status outcome clearly (success or failed).
2. Return important response fields directly.
3. If request fails, provide likely causes and a corrected command.

Common failure causes:

• Invalid or expired API key
• Malformed JSON quoting
• URL missing from copied share text
• Upstream video access or parsing issues

If response indicates invalid token/key (for example code: -1 and message like 令牌无效), guide the user to:

• https://devtool.uk/plugin
• Purchase/renew a valid key there (no free key is provided).

Missing API Key standard reply (required)

Output format

Use this structure in responses:

# Douyin Transcription Request
- Endpoint: https://coze-js-api.devtool.uk/transcribe-douyin
- URL input: <value used>
- API key source: <env: DOUYIN_TRANSCRIBE_API_KEY>

## Request
<exact exec bash scripts/transcribe_douyin.sh command>

## Result
<concise summary of response or error>

## Next Step
<one practical fix or follow-up>

Examples

Example 1: Input: "Transcribe this: https://v.douyin.com/gtSMSkIh3p0/" Output behavior: Read key from DOUYIN_TRANSCRIBE_API_KEY, run exec bash scripts/transcribe_douyin.sh "https://v.douyin.com/gtSMSkIh3p0/", then summarize response.

Example 2: Input: "4.12 ... https://v.douyin.com/gtSMSkIh3p0/ ... 打开Dou音搜索 ..." Output behavior: Pass the full share text into scripts/transcribe_douyin.sh, let the script send the JSON request, and report result.

Safety and privacy

• Never leak full secret keys in logs when not required.
• If sharing command output, redact sensitive key values unless user explicitly asks for full raw output.
• Do not invent successful transcripts when the API fails; report the failure honestly.
