}

Quickstart (60 seconds)

1. Get a free API key at https://trendsapi.ai/#get-key - 100 requests/month, no credit card.

2. Make your first call:

curl -X POST https://api.trendsapi.ai/api \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"mode": "get_time_series", "source": "app downloads", "keyword": "chatgpt"}'

Python:

import requests

res = requests.post(
    "https://api.trendsapi.ai/api",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"mode": "get_growth", "source": "app downloads", "keyword": "chatgpt",
          "percent_growth": ["3M", "12M"]},
)
print(res.json())

Node.js:

const res = await fetch("https://api.trendsapi.ai/api", {
  method: "POST",

The three modes

Why teams switch

Use cases

• ASO: track your app's chart position and category movement over time
• Competitive intel: watch a competitor's download trajectory after each release
• Investing: app download momentum as a signal for public mobile companies
• Product research: validate category demand before building

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 app store data does Trends API provide?

Android download estimates and chart rankings (via AppBrain) as time series, plus three live feeds: App Store Top Free, App Store Top Paid and Google Play top apps.

Can I track apps I do not own?

Yes. Store consoles only show your own apps; Trends API works for any public app, which is the point of competitive tracking.

Do you cover iOS downloads?

iOS coverage is chart positions (Top Free / Top Paid feeds). Download estimates are Android via AppBrain. Both are queryable through the same endpoint.

How do I query an app?

For keyword sources use app downloads or app rankings with the app's Android bundle ID (e.g. com.openai.chatgpt). For live charts use get_top_trends with the feed type.

How fresh is the data?

Charts update through the day; download and ranking series update on their source cadence. Every response includes a timestamp.
