@ssut/tiktok-api

Fully-typed TikTok web API client that REALLY works—handles URL signing, msToken rotation, retries, video downloads with format detection, and helpers for profiles, posts, and challenges.

Highlights

• Official TikTok web endpoints with automatic URL signing handled for you
• msToken extraction/rotation, retry with backoff, proxy support
• Video download with detailed format information (resolution, codec, watermark status)
• Dual builds (ESM + CJS) with full TypeScript types
• Pagination helpers for posts, followers, following, comments, and challenges

Installation

npm install @ssut/tiktok-api
npm install axios async-retry https-proxy-agent

Quick Start

import { TikTokClient, PostItemRequestType } from "@ssut/tiktok-api";

const client = new TikTokClient({ region: "US" });

// Get user profile
const user = await client.getUser("username");

// Get user posts
const posts = await client.getUserPosts(user.data?.userInfo.user.secUid ?? "", {
  postLimit: 10,
  requestType: PostItemRequestType.Popular,
});

// Get post comments
const comments = await client.getPostComments("7574735526134058262", 20);

// Download video with format detection
const download = await client.downloadVideo("https://www.tiktok.com/@zachking/video/6768504823336815877");
if (download.status === "success" && download.result?.type === "video") {
  console.log("Available formats:", download.result.video.formats);
  // Formats include resolution, codec (h264/h265), watermark status, etc.
}

• getUser(username, overrides?)
• getUserPosts(secUid, { postLimit?, nextCursor?, requestType? } & overrides?)
• getUserFollowers(secUid, { followerLimit?, count?, cursor? } & overrides?)
• getUserFollowing(secUid, { followingLimit?, count?, cursor? } & overrides?)

Client Options

• region (required) – e.g. "US"
• proxy (optional) – HTTP proxy URL for all requests
• msToken (optional) – seed token; auto-rotates afterward
• tiktokApiHost (optional) – custom API host (defaults to "api16-normal-c-useast1a.tiktokv.com")

Request Overrides

All methods support optional request overrides for per-request configuration:

// Use proxy for specific request
await client.getUser("username", {
  proxy: "http://proxy.example.com:8080",
});

// Disable proxy for specific request (if set globally)
await client.downloadVideo(url, false, {
  proxy: null,
});

// Override region for specific request
await client.getPost(itemId, {
  region: "UK",
});

Video Download Features

The downloadVideo method provides rich format information:

const result = await client.downloadVideo(url);

if (result.status === "success" && result.result?.type === "video") {
  const formats = result.result.video.formats;

  // Each format includes:
  for (const format of formats || []) {
    console.log({
      url: format.url, // Direct download URL
      resolution: format.resolution, // e.g., "1080p", "720p", "480p"
      format_id: format.format_id, // e.g., "play_addr", "download_addr"
      format_note: format.format_note, // e.g., "Direct video", "Download video (watermarked)"
      vcodec: format.vcodec, // e.g., "h264", "h265"
      width: format.width, // Video width in pixels
      height: format.height, // Video height in pixels
      has_watermark: format.has_watermark, // Whether video has TikTok watermark
      quality: format.quality, // Quality level
      bitrate: format.bitrate, // Bitrate (if available)
      fps: format.fps, // Frames per second (if available)
    });
  }
}
