}SocialAPI.ai is the social media API for the full loop: publish content across every major platform, read every comment, and reply to every DM through a single unified REST API. It covers Instagram, Facebook, Threads, TikTok, YouTube, X/Twitter, and LinkedIn, with Google Business Profile (reviews and local posts) coming soon. It is MCP-native and can be used directly as a tool by AI agents running on any MCP-compatible framework.
One endpoint for all your platforms
Every platform has its own auth, its own pagination, its own rate limits. I spent more time fighting APIs than building my product. So I built one API that handles all of them.
Publish, read, and reply across 8 platforms. One API key, one JSON shape, one error format.
One POST request. Your content goes to Instagram, Facebook, TikTok, YouTube, X, and LinkedIn. Failed? Built-in retry handles it.
Instagram comments, TikTok mentions, and Facebook DMs share the exact same JSON shape. Google Business reviews are coming soon to the same schema.
Listed on Smithery, Composio, MCP.so. Your Claude or GPT agent calls social_api_reply the same way it calls any other tool.
We store only what's needed to deliver the service: post metadata, delivery status, and engagement metrics. Your original content stays on the platforms.
New Instagram comment, Facebook DM, TikTok mention: they all arrive at the same endpoint, same JSON envelope. One handler covers all platforms.
Token expired? 401. Rate limited? 429. Not supported? 501. Same codes, same shape, every platform. One try/catch block.
Every platform returns the same JSON. One Bearer token to publish posts, read comments, and reply to DMs, whether you're on Instagram, TikTok, or Facebook.
from socialapi import SocialAPI
client = SocialAPI(api_key="sapi_key_...")
# List connected accounts
accounts = client.accounts.list()
# List posts with comments
posts = client.comments.list_posts(account_id="acc_ig_001").data
last_post = posts[0]
for comment in last_post.list_comments():
if "spam" in comment.text:
comment.hide()
else:
comment.reply(text="Thanks!")
# Publish a post to multiple platforms
post = client.publishing.create(
text="Hello from the API!",
targets=[
{"account_id": "acc_ig_001"},
{"account_id": "acc_fb_002"},
],
)Most APIs help you push content out. Few help you handle what comes back: comments, DMs, reviews, mentions. Here's how SocialAPI.ai stacks up on the engagement side.

// who's building on it
If you've ever quoted a customer six weeks to add a second platform, this section is for you.
You're building an inbox tool, a review aggregator, a creator dashboard. Your customers want Instagram, Facebook, and TikTok on day one. Maintaining three SDKs, three OAuth flows, and three webhook formats is a team you don't have.
One OAuth. One webhook. One JSON shape.
Your agent reads an Instagram DM, drafts a reply, posts a comment on Facebook, and pulls last week's Facebook mentions, all in the same run. No glue code, no per-platform tool definitions.
75 MCP tools, every endpoint mirrored.
Your customers DM you on Instagram, comment on TikTok, and tag you on Facebook. Today your team checks four tabs. One webhook fires them all into your triage tool with the same JSON shape, and you reply through the same endpoint.
Comments, DMs, mentions: one inbox.

FAQ
Everything you need to know before integrating.
SocialAPI.ai supports 7 platforms: Instagram, Facebook, Threads, TikTok, YouTube, X/Twitter, and LinkedIn, with Google Business Profile (reviews and local posts) coming soon. All platforms return the same Interaction JSON shape, giving you one schema regardless of source.
Yes. The Free plan gives you 2 brands, 10 posts/month, and 50 interactions/month across all platforms, including replies, DMs, and the MCP server. No credit card required. All paid plans include unlimited posts and interactions.
A brand groups all social accounts for one business, client, or project. Connect Instagram, TikTok, LinkedIn and more, it counts as one brand. Each brand can have one account per platform.
The Free plan has monthly limits (10 posts, 50 interactions). Once reached, write API calls return a 429 error until the limit resets at the start of your next billing period. All paid plans have unlimited posts and interactions, so there are no limits to hit. Read calls (get comments, get reviews, etc.) are always unaffected on all plans.
The MCP (Model Context Protocol) server exposes every API capability as a typed tool your AI agent can call, including social_api_list_comments, social_api_send_dm, social_api_reply_to_review, and more. It is listed on every major MCP marketplace (Smithery, Composio, MCP.so, PulseMCP, and others) and works with any MCP-compatible host including Claude, GPT-4o, and open-source orchestrators.
Yes. You can upgrade or downgrade at any time. Upgrades take effect immediately; downgrades apply at the next billing cycle.
