# Weekly Channel Digest → Ghost/Substack Draft

> Turn a channel's week into a ready-to-publish newsletter draft.

A ready-to-use skill for AI agents (Claude, Codex, OpenClaw, Hermes, and others).
It uses **TranscriptAPI** to pull YouTube transcripts — your agent does the
thinking itself, so all you need is a TranscriptAPI key (no separate AI key).

## What it does
Once a week it pulls a channel's new videos, transcribes and summarizes each, assembles a Markdown digest, and sends it to your Ghost, Substack, or webhook as a draft — never auto-published.

## How it works
1. You pick a channel and your draft endpoint.
2. Each week it gathers the channel's new videos.
3. It transcribes and summarizes each into a Markdown digest.
4. It saves the digest as a draft for you to review and publish.

## The TranscriptAPI calls
```
GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=<YOUTUBE_URL>
Authorization: Bearer <YOUR_TRANSCRIPTAPI_KEY>
```
```
GET https://transcriptapi.com/api/v2/youtube/channel/latest?channel=<CHANNEL>
Authorization: Bearer <YOUR_TRANSCRIPTAPI_KEY>
```

Transcript response shape:
```json
{ "video_id": "...", "language": "en", "transcript": [ { "text": "...", "start": 0.0, "duration": 1.95 } ] }
```

## What you need
- A **TranscriptAPI key** — free tier includes 100 credits, no credit card. Get one: https://transcriptapi.com/signup
- Nothing else: your agent does the reasoning (summarizing, extracting, classifying) natively — no extra AI API key required.

## Notes
- 1 TranscriptAPI credit per successful transcript.
