The three modes

Mode	What it returns	Needs a keyword?
get_time_series	Historical hashtag volume as a normalized 0-100 series	yes
get_growth	Growth % over 3M / 6M / 12M / 5Y windows	yes
get_top_trends	Live trending feeds (21 of them)	no

Why teams switch

	TikTok developer API	Trends API
TikTok API approval	required, slow	not needed
Hashtag volume history	not exposed	weekly + daily series
Trending hashtags feed	manual	one call
Cross-platform compare	no	same 0-100 scale as Google, YouTube, Amazon
Free tier	n/a	100 requests/month

Use cases

• Content strategy: spot hashtags rising before they saturate the For You page
• Brand monitoring: track a brand or product hashtag's volume over time
• Ecommerce: catch TikTok Shop product trends while they are still early
• Agencies: prove to clients which hashtags actually grew, with numbers

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):

{
  "mcpServers": {
    "trendsapi": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.trendsapi.ai/mcp", "--header", "Authorization:${AUTH_HEADER}"],
      "env": { "AUTH_HEADER": "Bearer YOUR_API_KEY" }
    }
  }
}

Claude.ai (browser): Settings -> Connectors -> Add custom connector -> https://api.trendsapi.ai/mcp

Then ask things like:

How did "creatine gummies" grow on TikTok vs Google over the last 12 months?
What is trending on YouTube right now?

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.
