late-sdk
The official Python library for the Zernio API
Decision gist · record as of 2026-08-14
Yes. The SDK is actively maintained, has no known vulnerabilities, low install friction, and a permissive Apache-2.0 license. Install it if you need to publish to multiple social platforms from Python code. The unified API simplifies multi-platform workflows compared to managing separate integrations. Verify that platform coverage and pricing match your use case before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires an API key (set via LATE_API_KEY or ZERNIO_API_KEY environment variable or passed explicitly) and connected social media accounts.
- Low friction install with only two runtime dependencies (httpx, pydantic).
- Active maintenance with latest release on 2026-08-14.

What it is and what it does
This is an official Python SDK for publishing and managing social media content across 16 major platforms through a single unified API. Instead of integrating separately with each platform, you write one call and it routes your post to whichever accounts you specify, with optional platform-specific content customization. The SDK handles authentication, scheduling, media upload, and analytics retrieval.
It wraps httpx for HTTP requests and uses pydantic for request/response validation. The library supports both synchronous and asynchronous workflows, bulk operations from CSV, and detailed error handling with specific exception types. Backward compatibility is maintained—old imports from the 'late' package still work alongside the new namespace.
Use it for
- Publish a single post to multiple platforms simultaneously with one API call.
- Schedule posts across multiple platforms for a specific date and time.
- Upload media once and distribute to multiple platforms with platform-specific metadata.
- Retrieve analytics and engagement metrics across all connected accounts.
- Bulk import and schedule posts from CSV across social media accounts.
- Customize post content per platform with different text and media per destination.
