注意:本技能会将抖音分享链接 / 分享文案 与 API Key 发送到 dy-caption 服务,请确认你信任该服务后再使用。
认证
调用接口前需要先准备 API Key:
export DY_CAPTION_API_KEY="你的 API Key"
快速使用
# 提交转写任务
curl -X POST https://api.dycaption.cn/api/v1/transcribe \
-H "X-API-Key: $DY_CAPTION_API_KEY" \
-H "Content-Type: application/json" \
-d '{"input":"7.53 复制打开抖音,看看【示例】 https://v.douyin.com/xxxx/"}'
# 查询余额
curl -X GET https://api.dycaption.cn/api/v1/credits \
-H "X-API-Key: $DY_CAPTION_API_KEY"
# 查询历史

Usage Guidance
Before installing: understand that this skill will send the Douyin share text/link and whatever API key you provide to api.dycaption.cn. The registry metadata is incomplete — you must set DY_CAPTION_API_KEY and have curl available, though those are not listed in the manifest. Only use this skill if you trust the external service. Recommendations: (1) verify the api.dycaption.cn domain and the upstream GitHub repo (https://github.com/xwchris/douyin-caption-cli) to inspect server/client code, (2) use a limited-scope or disposable API key, (3) avoid submitting sensitive content or credentials, and (4) ask the author or registry maintainer to update the skill metadata to list DY_CAPTION_API_KEY and curl so it's explicit what the skill requires.
Capability Analysis
Type: OpenClaw Skill
Name: dy-caption
Version: 1.0.0
The skill is a legitimate wrapper for the dy-caption service (api.dycaption.cn), designed to transcribe Douyin video audio to text. It uses standard curl commands to interact with documented API endpoints for transcription, credit checks, and history retrieval, and it transparently requires a user-provided API key (DY_CAPTION_API_KEY) as described in SKILL.md and README.md.
Capability Tags
Capability Assessment
Purpose & Capability
The skill's name/description (transcribe Douyin video audio) matches the SKILL.md instructions (call api.dycaption.cn). However the registry metadata omits dependencies that the SKILL.md requires: SKILL.md lists curl and expects an API key (DY_CAPTION_API_KEY), but the manifest declares no required binaries or env vars. This mismatch is incoherent and should be clarified.
Instruction Scope
SKILL.md gives concrete instructions to send the user's share link/share text and the DY_CAPTION_API_KEY to https://api.dycaption.cn and to poll for task results. That behavior is consistent with the stated purpose (a hosted transcription API) but it explicitly transmits user content and a credential to an external service — a privacy/data-exfiltration risk that users must accept before use.
Install Mechanism
This is an instruction-only skill with no install spec or code files, so nothing is written to disk by an installer. That's low install risk.
Credentials
The runtime requires a single API key (DY_CAPTION_API_KEY) to authenticate to the third-party service; that is proportionate for the feature. However the required env var is not declared in the registry metadata, and SKILL.md lists curl as required while the manifest lists no binaries — this missing declaration is an inconsistency and should be corrected so users know what they must provide.
Persistence & Privilege
The skill does not request always:true, does not modify other skills or system-wide settings, and has normal (non-persistent) invocation behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install dy-caption - After installation, invoke the skill by name or use
/dy-caption - Provide required inputs per the skill's parameter spec and get structured output
