Read and respond to comments, direct messages, mentions, and reviews from Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads through one REST API. Every platform returns the same Interaction JSON, and real-time webhooks push new events to your app.
Every social network has its own API, auth flow, rate limits, and message schema. A unified inbox API normalizes comments, DMs, mentions, and reviews from all of them into a single consistent shape, so you write your inbox logic once instead of maintaining eight brittle integrations.
Read, reply, hide, like, and delete comments across all connected platforms.
List conversations, read threads, and send replies through one messaging endpoint.
Track posts and stories that mention or tag your connected accounts.
Read and respond to Google Business Profile reviews through the same unified schema.
Receive real-time events for new comments, messages, and mentions with signed, retried delivery.
Every interaction returns the same Interaction JSON regardless of source platform.

List the latest interactions across every connected platform with one call. Comments, DMs, and mentions share the same schema; pagination and token refresh are handled for you.
Comments, DMs, mentions, and reviews from every platform are normalized into a single Interaction object. Your code reads author, text, timestamps, and IDs the same way whether the source is an Instagram comment or a LinkedIn message, so you build inbox UIs and automations once.
Subscribe once and receive signed webhook events for new comments, messages, and mentions across all connected accounts. SocialAPI.ai verifies platform signatures, deduplicates events, and retries delivery with exponential backoff so your inbox stays in sync.
Responding is symmetric with reading. Reply to a comment, send a DM, or hide a message through the same unified endpoints, and SocialAPI.ai handles per-platform rules like Instagram's 24-hour messaging window behind the scenes.
The same unified inbox is exposed as Model Context Protocol tools, so an AI agent can triage and respond to messages across every network without any platform-specific code.
Tools like Unipile and respond.io target end users with dashboards. SocialAPI.ai is an API-first unified inbox built for developers and AI agents, with a native MCP server and usage-based pricing.

SocialAPI.ai supports Instagram, Facebook, Threads, TikTok, YouTube, X/Twitter, Google Business Profile reviews, and LinkedIn. All return the same Interaction shape, so adding a platform does not change your code.
