# YouTube Data

YouTube data access via [TranscriptAPI.com](https://transcriptapi.com) — lightweight alternative to Google's YouTube Data API.

## Setup

If `$TRANSCRIPT_API_KEY` is not set, help the user create an account (100 free credits, no card):

**Step 1 — Register:** Ask user for their email.

```bash
node ./scripts/tapi-auth.js register --email USER_EMAIL
```

→ OTP sent to email. Ask user: _"Check your email for a 6-digit verification code."_

**Step 2 — Verify:** Once user provides the OTP:

```bash
node ./scripts/tapi-auth.js verify --token TOKEN_FROM_STEP_1 --otp CODE
```

> API key saved to `~/.openclaw/openclaw.json`. See **File Writes** below for details. Existing file is backed up before modification.

Manual option: [transcriptapi.com/signup](https://transcriptapi.com/signup) → Dashboard → API Keys.

## File Writes

The verify and save-key commands save the API key to `~/.openclaw/openclaw.json` (sets `skills.entries.transcriptapi.apiKey` and `enabled: true`). **Existing file is backed up to `~/.openclaw/openclaw.json.bak` before modification.**

To use the API key in terminal/CLI outside the agent, add to your shell profile manually:
`export TRANSCRIPT_API_KEY=<your-key>`
