Ship your YouTube integration in minutes, not months

Stop wrestling with YouTube's Data API. Zernio handles OAuth, rate limits, video processing, and API changes - so you can focus on building your product.

Why Zernio vs YouTube Data API?

Save 4-6 weeks of development time

Zernio API

Simple API key - start in 30 seconds
Automatic retries & queue management
Upload directly - we handle resumable uploads
Zero maintenance forever
One API for 17 platforms

YouTube Data API v3

Complex OAuth with Google Cloud Console setup
Strict quota limits requiring careful management
Resumable uploads with complex chunking logic
Frequent API deprecations require constant updates
Build separate integrations per platform

How It Works

Three steps to YouTube automation

1

Profile

default

YouTube

Connect your channel

Link your YouTube channel through our dashboard. One-click OAuth - we handle all the Google permissions.

2

POST /v1/posts

const { data } = await zernio.posts.createPost({
  body: {
    content: 'v2 walkthrough',
    mediaItems: [{ url: 'https://cdn.acme.com/launch.mp4' }],
    platforms: [
      { platform: 'youtube', accountId: 'acc_8f2a' },
    ],
    scheduledFor: '2027-01-15T14:30:00',
    timezone: 'Europe/Madrid',
  },
});

Build your integration

Use our simple REST API to upload videos with titles, descriptions, and thumbnails. Same pattern works for all 17 platforms.

We handle the rest

Zernio uploads at your scheduled time, handles resumable uploads, and notifies you via webhooks. You never touch YouTube's API directly.

You need a YouTube channel linked to your Google account

Features

Everything you need to ship YouTube features

Uploads

Publish videos and Shorts to YouTube, create playlists, and add a video to one on publish.

Schedule

Set a scheduled time and Zernio publishes the video at that moment.

Transcripts

Read the caption track YouTube already holds for any of your channel's videos as plain text with timed cues, including auto-generated ones.

Thumbnail

Set a custom thumbnail on your videos, which Zernio validates against YouTube's format and size rules before upload.

Comments

Read, reply to, and delete comments on your YouTube videos.

Analytics

Pull views, likes, and comments per video, with per-day watch time and subscriber changes.

Integrate

Three ways in. Same API behind all of them

Write it yourself with the SDKs, hand it to an agent over MCP, or run it from a shell.

import Zernio from '@zernio/node';

const zernio = new Zernio(); // reads ZERNIO_API_KEY

const { data: post } = await zernio.posts.createPost({

body: {

content: 'v2 walkthrough',

mediaItems: [{ type: 'video', url: 'https://cdn.acme.com/launch.mp4' }],

platforms: [

{

platform: 'youtube',

accountId: 'acc_xxx',

platformSpecificData: {

title: 'Zernio v2 walkthrough',

visibility: 'public',

madeForKids: false,

},

},

],

publishNow: true,

},

});
