Zernio MCP server

Zernio Python SDK

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

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")
