## Get Started

### 1. Get API Key

1. Sign up at [app.toughtongueai.com](https://app.toughtongueai.com)
2. Go to [Developer Portal → API Keys](https://app.toughtongueai.com/developer?tab=api-keys)
3. Create and save your token

<Warning>Never expose API tokens in client-side code. Proxy through your backend.</Warning>

### 2. Create a Scenario

Use [Scenario Studio](https://app.toughtongueai.com/advanced-scenario-create)
or the API:

```bash theme={null}
curl -X POST https://api.toughtongueai.com/api/public/scenarios \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "Sales Coach", "ai_instructions": "You are a skeptical VP..."}'
```

### 3. Choose Integration

**Iframe** — Embed directly:

```html theme={null}
<iframe src="https://app.toughtongueai.com/embed/SCENARIO_ID" allow="microphone"></iframe>
```

**API** — Build custom:

```javascript theme={null}
// Create session
const session = await fetch("/api/tough-tongue/sessions", {
  method: "POST",
  body: JSON.stringify({ scenario_id: "SCENARIO_ID" }),
}).then((r) => r.json());

// Redirect to session
window.location = session.embed_url;
```
