# YouTube Search

Search YouTube and fetch transcripts via [TranscriptAPI.com](https://transcriptapi.com).

## 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, generate a secure password.

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

→ OTP sent to email. Ask user: _"Check your email for a 6-digit verification code."_
⚠️ **SAVE THE PASSWORD** — you need it again in Step 2!

**Step 2 — Verify:** Once user provides the OTP (use SAME password from Step 1):

```bash
node ./scripts/tapi-auth.js verify --email USER_EMAIL --password SECURE_PASS --otp CODE --json
```

→ Returns `api_key` (starts with `sk_`).

**Step 3 — Save:** Store the key (auto-configures agent + shell):

```bash
node ./scripts/tapi-auth.js save-key --key API_KEY --json
```

→ Ready to use. Agent runtime picks up the key automatically.

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