Integrate DuckDuckGo search seamlessly into your n8n workflows with advanced pagination and human-like behavior. Get more results without hitting rate limits.

Package Exports

  • n8n-nodes-duckduckgo-search
  • n8n-nodes-duckduckgo-search/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (n8n-nodes-duckduckgo-search) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

DuckDuckGo n8n Node - Enhanced 2025 Edition

npm version License: MIT

A comprehensive n8n community node for seamless DuckDuckGo search integration with advanced pagination, enhanced error handling, and compatibility with 2025 DuckDuckGo API updates.

⚠️ Known Issues (January 2025)

🐛 DuckDuckGo Library Compatibility Issue

Status: ACTIVE ISSUE - Affects Web Search operation

  • Problem: DuckDuckGo has changed their website structure, causing the underlying duck-duck-scrape library to fail with error: "Cannot read properties of null (reading '1')"
  • Impact: Web Search returns empty results or errors
  • Cause: The library's regex patterns no longer match DuckDuckGo's new HTML structure
  • Affected Operations: Primarily Web Search (other operations may still work)
  • Timeline: This is an upstream library issue affecting many users globally

🔧 Current Workarounds

  1. Try Alternative Operations: Image Search, News Search, and other operations may still work
  2. Use Different Queries: Sometimes simpler queries work better
  3. Report Issues: Help us track which queries fail by reporting issues
  4. Check Updates: We're monitoring for duck-duck-scrape library updates

🎯 Resolution Status

  • Tracking: Issue is being tracked in the duck-duck-scrape repository
  • Alternative Solutions: We're investigating SearchAPI.io and other alternatives
  • Updates: This README will be updated when a fix is available

Rate Limiting

If you encounter rate limiting:

  • Increase delays between requests
  • Enable adaptive rate limiting
  • Use caching to reduce API calls

VQD Token Errors

For VQD token issues:

  • Tokens are automatically refreshed
  • Clear cache if problems persist
  • Enable debug mode for detailed logs

Empty Results

If getting empty results:

  • Check search terms for typos
  • Try different regions or time periods
  • Verify DuckDuckGo service availability

Debug Mode

Enable debug mode for detailed logging:

{
  "debugMode": true
}

All operations return structured data with consistent formatting:

{
  "sourceType": "web|image|news|video",
  "title": "Result title",
