Zernio

Zernio Python SDK

One API to post everywhere. 16 platforms, zero headaches.

The official Python SDK for the Zernio API — schedule and publish social media posts across Instagram, TikTok, YouTube, LinkedIn, X/Twitter, Facebook, Pinterest, Threads, Bluesky, Reddit, Snapchat, Telegram, WhatsApp, and Google Business Profile with a single integration.

Installation

pip install zernio-sdk

Quick Start

from zernio import Zernio

Reads ZERNIO_API_KEY from environment (or pass explicitly)

client = Zernio()

Publish to multiple platforms with one call

post = client.posts.create( content="Hello world from Zernio!", platforms=[ {"platform": "twitter", "accountId": "acc_xxx"}, {"platform": "linkedin", "accountId": "acc_yyy"}, {"platform": "instagram", "accountId": "acc_zzz"}, ], publish_now=True, )

print(f"Published to {len(post'post')} platforms!")

Configuration

client = Zernio(

api_key="your-api-key", # Or set ZERNIO_API_KEY env var base_url="https://zernio.com/api", # Optional, this is the default timeout=30.0, # Optional, request timeout in seconds )

Examples

Schedule a Post

post = client.posts.create(

content="This post will go live tomorrow at 10am", platforms=[{"platform": "instagram", "accountId": "acc_xxx"}], scheduled_for="2025-02-01T10:00:00Z", )

Platform-Specific Content

Customize content per platform while posting to all at once:

post = client.posts.create(

content="Default content", platforms=[ { "platform": "twitter", "accountId": "acc_twitter", "platformSpecificContent": "Short & punchy for X", }, { "platform": "linkedin", "accountId": "acc_linkedin", "platformSpecificContent": "Professional tone for LinkedIn with more detail.", }, ], publish_now=True, )

Upload Media

# Option 1: Direct upload (simplest)

result = client.media.upload("path/to/video.mp4") media_url = result["publicUrl"]

Option 2: Upload from bytes

result = client.media.upload_bytes(video_bytes, "video.mp4", "video/mp4") media_url = result["publicUrl"]

Create post with media

post = client.posts.create( content="Check out this video!", media_urls=[media_url], platforms=[ {"platform": "tiktok", "accountId": "acc_xxx"}, {"platform": "youtube", "accountId": "acc_yyy", "youtubeTitle": "My Video"}, ], publish_now=True, )

Get Analytics

data = client.analytics.get(period="30d")

print("Analytics:", data)

List Connected Accounts

data = client.accounts.list()

for account in data["accounts"]: print(f"{account['platform']}: @{account['username']}")

Async Support

import asyncio

from zernio import Zernio

async def main(): async with Zernio(api_key="your-api-key") as client: posts = await client.posts.alist(status="scheduled") print(f"Found {len(posts['posts'])} scheduled posts")

asyncio.run(main())

Error Handling

from zernio import Zernio, ZernioAPIError, ZernioRateLimitError, ZernioValidationError

client = Zernio(api_key="your-api-key")

try: client.posts.create(content="Hello!", platforms=[...]) except ZernioRateLimitError as e: print(f"Rate limited: {e}") except ZernioValidationError as e: print(f"Invalid request: {e}") except ZernioAPIError as e: print(f"API error: {e}")

Migration from Late

All old names continue to work. No code changes are required:

# Old style (still works)

from late import Late, LateAPIError client = Late(api_key="...")

New style

from zernio import Zernio, ZernioAPIError client = Zernio() # reads ZERNIO_API_KEY env var

Both from zernio import ... and from late import ... work identically. The LATE_API_KEY environment variable is also still supported as a fallback when ZERNIO_API_KEY is not set.
