Reddit Trends API - discussion volume & subreddit growth as JSON

Reddit trend data as clean JSON: subreddit subscriber growth, discussion volume time series and live hot posts from one REST endpoint. No OAuth, no app registration, no rate-limit juggling.

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

The three modes

Why teams switch

Use cases

• Investment research: track ticker and sector discussion volume as an alternative-data signal
• Brand listening: measure mention growth after launches or PR events
• Community research: find subreddits growing fastest in your niche
• Content marketing: mine rising pain points before they hit mainstream search

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" }
    }
  }
}

FAQ

What Reddit data does Trends API provide?

Subreddit subscriber counts and discussion volume as normalized time series, growth percentages over 3M/6M/12M/5Y, plus live Reddit Hot Posts and r/worldnews feeds.

Do I need to register a Reddit app?

No OAuth, no client ID, no redirect URIs. Your Trends API key is the only credential.

Can I track a stock ticker?

Yes. Pass the ticker or company name as the keyword to get discussion volume over time - a common alternative-data input for equity research.

How does the 0-100 score work for Reddit?

Each series is rescaled against its own history: 100 is the peak of the requested window. That makes Reddit discussion volume directly comparable to Google search interest or TikTok hashtag volume.

How often does the hot-posts feed update?

Continuously through the day. Every response includes a timestamp so you know exactly how fresh it is.
