PostLake is a social media API and automation platform designed for AI agents, developers, creators, and teams. It provides one unified interface for observing, publishing, scheduling, engaging, and measuring social media activity across X, LinkedIn, Instagram, TikTok, Facebook, Threads, Bluesky, YouTube, and Pinterest. By standardizing platform-specific requirements, PostLake helps users manage multiple social networks through a single integration.

Key features include REST API access, a hosted Model Context Protocol (MCP) server, managed social account connections, media uploads, cross-platform publishing, scheduling, analytics, webhooks, and pre-publication validation. PostLake also supports draft workflows, human approval controls, posting limits, audit visibility, and idempotent publishing to help prevent duplicate posts when an agent retries an operation. Developers can integrate the platform with AI agents, automation workflows, LangGraph, CrewAI, TypeScript applications, and other custom systems for centralized social media management.
