Stream API Reference
Upload, playback, live streaming, and management APIs.
Upload APIs
Direct Creator Upload (Recommended)
Backend: Create upload URL (SDK)
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
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
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)
<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
// 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
// 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/${videoId}/thumbnails/thumbnail.gif`
Signed URLs
// Low volume (<1k/day): Use API
async function getSignedToken(accountId: string, videoId: string, apiToken: string) {
const response = await fetch(`https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/token`, {
method: 'POST',
headers: { Authorization: `Bearer ${apiToken}`, 'Content-Type': 'application/json' },
body: JSON.stringify({
exp: Math.floor(Date.now() / 1000) + 3600,
accessRules: [{ type: 'ip.geoip.country', action: 'allow', country: ['US'] }],
}),
})
return (await response.json()).result.token
}
// High volume: Self-sign with RS256 JWT (see "Self-Sign JWT" in patterns.md)
Captions & Clips
Upload Captions
async function uploadCaption(
accountId: string,
videoId: string,
apiToken: string,
language: string,
captionFile: File,
) {
const formData = new FormData()
formData.append('file', captionFile)
return fetch(`https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/captions/${language}`, {
method: 'PUT',
headers: { Authorization: `Bearer ${apiToken}` },
body: formData,
}).then((r) => r.json())
}
Generate AI Captions
// TODO: Requires Workers AI integration - see workers-ai reference
async function generateAICaptions(accountId: string, videoId: string, apiToken: string) {
return fetch(`https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/${videoId}/captions/generate`, {
method: 'POST',
headers: { Authorization: `Bearer ${apiToken}`, 'Content-Type': 'application/json' },
body: JSON.stringify({ language: 'en' }),
}).then((r) => r.json())
}
Clip Video
async function clipVideo(accountId: string, videoId: string, apiToken: string, startTime: number, endTime: number) {
return fetch(`https://api.cloudflare.com/client/v4/accounts/${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
// 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,
})
