TikTok Trends API - hashtag volume & growth as JSON

TikTok trend data as clean JSON: hashtag volume time series, growth rates and live trending hashtags, sounds and searches from one REST endpoint. No TikTok API approval, no scraping.

One endpoint. One API key. One normalized 0-100 trend score you can compare against 14 other platforms.

Why teams switch

Use cases

Use it from your AI assistant (MCP)

The same API key powers the Trends API MCP server, so Claude, Cursor, VS Code, ChatGPT and any MCP-compatible client can query this data in natural language.

+ Add to Cursor (one click)

Cursor / Windsurf / Cline (~/.cursor/mcp.json or equivalent):

{
  "mcpServers": {
    "trendsapi": {
      "url": "https://api.trendsapi.ai/mcp",
      "transport": "http",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

VS Code / GitHub Copilot (.vscode/mcp.json):

{
  "servers": {
    "trendsapi": {
      "type": "http",
      "url": "https://api.trendsapi.ai/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Claude Desktop (claude_desktop_config.json):

FAQ

What TikTok data does Trends API provide?

Hashtag volume over time (normalized 0-100), growth percentages over 3M/6M/12M/5Y windows, and live feeds: trending hashtags, trending searches and TikTok Shop hot products.

Do I need a TikTok developer account?

No. There is no OAuth flow, no app review and no approval wait. One Trends API key covers TikTok and every other source.

How early can I detect a TikTok trend?

Daily data for the last 30 days plus weekly history lets you catch early growth spikes before a hashtag reaches mainstream saturation. TikTok spikes typically lead Google Search interest by 2-4 weeks.

Are hashtags case-sensitive?

No. booktok, BookTok and #booktok all resolve to the same signal.

Can I compare TikTok against other platforms?

Yes - that is the point of the product. Query tiktok, youtube and google search for the same keyword and compare normalized scores directly.
