# Stream API Reference

Upload, playback, live streaming, and management APIs.

## Upload APIs

### Direct Creator Upload (Recommended)

**Backend: Create upload URL (SDK)**
```typescript
import Cloudflare from 'cloudflare';

const client = new Cloudflare({ apiToken: env.CF_API_TOKEN });

const uploadData = await client.stream.directUpload.create({
  account_id: env.CF_ACCOUNT_ID,
  maxDurationSeconds: 3600,
  requireSignedURLs: true,
  meta: { creator: 'user-123' }
});
// Returns: { uploadURL: string, uid: string }
```

**Frontend: Upload file**
```typescript
async function uploadVideo(file: File, uploadURL: string) {
  const formData = new FormData();
  formData.append('file', file);
  return fetch(uploadURL, { method: 'POST', body: formData }).then(r => r.json());
}
```

### Upload from URL

```typescript
const video = await client.stream.copy.create({
  account_id: env.CF_ACCOUNT_ID,
  url: 'https://example.com/video.mp4',
  meta: { name: 'My Video' },
  requireSignedURLs: false
});
```

## Playback APIs

### Embed Player (iframe)

```html
<iframe
  src="https://customer-<CODE>.cloudflarestream.com/<VIDEO_ID>/iframe?autoplay=true&muted=true"
  style="border: none;" height="720" width="1280"
  allow="accelerometer; gyroscope; autoplay; encrypted-media; picture-in-picture;"
  allowfullscreen="true"
></iframe>
```

### HLS/DASH Manifest URLs

```typescript
// HLS
const hlsUrl = `https://customer-<CODE>.cloudflarestream.com/${videoId}/manifest/video.m3u8`;

// DASH
const dashUrl = `https://customer-<CODE>.cloudflarestream.com/${videoId}/manifest/video.mpd`;
```

### Thumbnails

```typescript
// At specific time (seconds)
const thumb = `https://customer-<CODE>.cloudflarestream.com/${videoId}/thumbnails/thumbnail.jpg?time=10s`;

// By percentage
const thumbPct = `https://customer-<CODE>.cloudflarestream.com/${videoId}/thumbnails/thumbnail.jpg?time=50%`;

// Animated GIF
const gif = `https://customer-<CODE>.cloudflarestream.com/${videoId}/thumbnails/thumbnail.gif`;
```

## Signed URLs

```typescript
// Low volume (<1k/day): Use API
async function getSignedToken(accountId: string, videoId: string, apiToken: string) {
  const response = await fetch(
    `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/token`,
    {
      method: 'POST',
      headers: { 'Authorization': `Bearer ${apiToken}`, 'Content-Type': 'application/json' },
      body: JSON.stringify({
        exp: Math.floor(Date.now() / 1000) + 3600,
        accessRules: [{ type: 'ip.geoip.country', action: 'allow', country: ['US'] }]
      })
    }
  );
  return (await response.json()).result.token;
}

// High volume: Self-sign with RS256 JWT (see "Self-Sign JWT" in patterns.md)
```

## Captions & Clips

### Upload Captions

```typescript
async function uploadCaption(
  accountId: string, videoId: string, apiToken: string,
  language: string, captionFile: File
) {
  const formData = new FormData();
  formData.append('file', captionFile);
  return fetch(
    `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/captions/${language}`,
    {
      method: 'PUT',
      headers: { 'Authorization': `Bearer ${apiToken}` },
      body: formData
    }
  ).then(r => r.json());
}
```

### Generate AI Captions

```typescript
// TODO: Requires Workers AI integration - see workers-ai reference
async function generateAICaptions(accountId: string, videoId: string, apiToken: string) {
  return fetch(
    `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/captions/generate`,
    {
      method: 'POST',
      headers: { 'Authorization': `Bearer ${apiToken}`, 'Content-Type': 'application/json' },
      body: JSON.stringify({ language: 'en' })
    }
  ).then(r => r.json());
}
```

### Clip Video

```typescript
async function clipVideo(
  accountId: string, videoId: string, apiToken: string,
  startTime: number, endTime: number
) {
  return fetch(
    `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/clip`,
    {
      method: 'POST',
      headers: { 'Authorization': `Bearer ${apiToken}`, 'Content-Type': 'application/json' },
      body: JSON.stringify({
        clippedFromVideoUID: videoId,
        startTimeSeconds: startTime,
        endTimeSeconds: endTime
      })
    }
  ).then(r => r.json());
}
```

## Video Management

```typescript
// List videos
const videos = await client.stream.videos.list({
  account_id: env.CF_ACCOUNT_ID,
  search: 'keyword' // optional
});

// Get video details
const video = await client.stream.videos.get(videoId, {
  account_id: env.CF_ACCOUNT_ID
});

// Update video
await client.stream.videos.update(videoId, {
  account_id: env.CF_ACCOUNT_ID,
  meta: { title: 'New Title' },
  requireSignedURLs: true
});

// Delete video
await client.stream.videos.delete(videoId, {
  account_id: env.CF_ACCOUNT_ID
});
```
