SocialAPI.ai is a REST social media API for Node.js and TypeScript. Call it with fetch or axios using a bearer API key to read comments, send DMs, publish posts, and reply to reviews across eight networks, with fully typed normalized JSON and no per-platform SDKs.
Every network has its own npm SDK with a different client, auth flow, and response model, so a project that spans several platforms maintains several integrations. SocialAPI.ai replaces them with one REST API you call using fetch or axios. The same request returns the same typed JSON for every platform, so you build the integration once.
Call the API with native fetch, axios, or any HTTP client. No SDK to install.
List, reply to, hide, and like comments across all connected platforms.
Read conversations and send replies through one messaging endpoint.
Create and schedule posts across every network from a single request.
Receive real-time events in your Node service the moment something happens.
Read and reply from Node.js
1const API = "https://api.social-api.ai/v1";
2const headers = {
3 Authorization: "Bearer sapi_key_...",
4 "Content-Type": "application/json",
5};
6
7// List comments on a post (any platform, same shape)
8const res = await fetch(`${API}/accounts/${accountId}/posts/${postId}/comments`, { headers });
9const { data: comments } = await res.json();
10
11// Reply to the first comment
12await fetch(`${API}/accounts/${accountId}/interactions/${comments[0].id}/reply`, {
13 method: "POST",
14 headers,
15 body: JSON.stringify({ text: "Thanks for your comment!" }),
16});
Authenticate with a bearer token and call the endpoints with fetch. The same code shape works for every connected platform because responses are normalized.
There is no SocialAPI.ai npm package to learn. Call the API with native fetch or axios from Node, Bun, Deno, or an edge function. Because it is plain REST, it drops into any JavaScript or TypeScript project without generated clients or extra dependencies.
SocialAPI.ai normalizes Instagram, Facebook, TikTok, LinkedIn, YouTube, X, and Threads, so the function that reads comments or posts a reply is identical across platforms. You write and type it once instead of maintaining a separate client per network.
Every endpoint returns the same normalized JSON, so you can model the response once with a TypeScript type and reuse it everywhere. Stable, reversible interaction IDs make read-then-reply flows easy to type and test.
If you are building an AI agent in JavaScript or TypeScript, SocialAPI.ai also exposes a Model Context Protocol server so the agent can call social tools directly. See the Social Media API for AI Agents page at https://social-api.ai/solutions/social-media-api-for-ai-agents.
FAQ
The best social media API for Node.js is one REST API that covers every network with a consistent, typed response shape, so you avoid maintaining a separate npm SDK per platform. SocialAPI.ai does this: call it with fetch or axios and read or respond across Instagram, TikTok, LinkedIn, and more.
Connect your Instagram account in the SocialAPI.ai dashboard, then send an authenticated POST to the publishing endpoint with fetch or axios. The same request publishes to Instagram, TikTok, LinkedIn, and the other supported networks because the API is normalized.
Yes. SocialAPI.ai is plain REST that returns the same normalized JSON for every platform, so you model it once with a TypeScript type and reuse it across networks. There is no per-platform client to wrap or maintain.
Send an authenticated GET with fetch to the comments or conversations endpoint and read the normalized JSON. The same call returns data for Instagram, TikTok, and the other supported networks, so one function covers them all.
Yes. Combine SocialAPI.ai webhooks with the reply and DM endpoints to build a bot that reacts to comments and messages in real time. It runs on Node, Bun, Deno, or an edge function, and there is a free tier with an instant API key.
