Zernio Python SDK
One API to post everywhere. 14 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'])} 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.
