# zernio-sdk — The official Python library for the Zernio API

License: permissive · Maintenance: active · Downloads: 165.3K/mo

## What it is and what it does

Zernio SDK is a Python client library for the Zernio API that abstracts away the complexity of managing separate integrations with multiple social media platforms. Instead of writing platform-specific code for Twitter, Instagram, LinkedIn, TikTok, and others, you write once and publish everywhere through a single unified interface. The SDK handles authentication, request formatting, and response parsing for each platform.

The library supports the full lifecycle of social media management: creating and scheduling posts, uploading media, customizing content per platform, managing connected accounts, retrieving analytics, and editing or unpublishing published content. It includes both synchronous and asynchronous APIs, built on httpx for HTTP transport and pydantic for request/response validation. The SDK is actively maintained, supports current Python versions (3.10–3.13), and carries no known security vulnerabilities.

Use it for:

- Publish a single blog post or announcement to Twitter, LinkedIn, and Facebook simultaneously with one API call
- Schedule content across multiple platforms for a specific time without writing platform-specific scheduling logic
- Customize post text per platform (e.g., short for Twitter, detailed for LinkedIn) while publishing in one operation
- Upload videos and images once, then distribute them across TikTok, YouTube, Instagram, and other video platforms
- Retrieve aggregated analytics across all connected accounts to track engagement and reach in one place
- Migrate from a legacy social posting tool by replacing multiple platform SDKs with a single unified client

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Unified Python client for publishing social media posts across 16 platforms (Instagram, TikTok, YouTube, LinkedIn, X/Twitter, Facebook, Pinterest, Threads, Bluesky, Reddit, Snapchat, Telegram, WhatsApp, Google Business Profile, and others) with a single API call.

Yes. The SDK is actively maintained, has low install friction, carries no known vulnerabilities, and solves a real problem for anyone managing multiple social media accounts. The permissive Apache-2.0 license poses no restrictions. Install if you need to publish to multiple platforms programmatically; skip if you only target one or two platforms or prefer manual posting.

## Install

pip install zernio-sdk
uv add zernio-sdk
poetry add zernio-sdk

## Installing zernio-sdk

Before you install: Low install friction with only two runtime dependencies (httpx and pydantic). Active maintenance with a release on 2026-08-14 and recent repository activity. Supports Python 3.10 through 3.13.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions, making it suitable for most production applications.

Quickstart:

pip install zernio-sdk

from zernio import Zernio

client = Zernio()  # reads ZERNIO_API_KEY from environment
post = client.posts.create(
    content="Hello world",
    platforms=[{"platform": "twitter", "accountId": "acc_xxx"}],
    publish_now=True,
)

Requires a valid Zernio API key (via ZERNIO_API_KEY environment variable or explicit parameter) and connected social media accounts.

Verify before relying:

- Rate limiting behavior and quotas for bulk operations across multiple platforms
- Latency and reliability characteristics when publishing to all 16 platforms simultaneously
- Whether media upload size limits and supported formats are documented per platform
