KWFinder

KWFinder is Mangools' keyword research tool. The API gives you programmatic access to the same keyword data that powers the KWFinder app: search volumes, keyword difficulty scores, CPC, trend history, competitor keyword profiles, and long-tail suggestions.

What you can do

• Discover keywords — fetch related keyword suggestions for any seed keyword, filtered by location and language.
• Analyze competitors — pull the keyword profile of any competing domain or URL.
• Import and score keywords — submit your own keyword lists and get back metrics (volume, KD, CPC, trends).
• Fetch SERP data — retrieve the SERP results for a keyword to see who is ranking.
• Analyze keyword gaps — find keywords a competitor ranks for that you don't.
• Manage keyword lists — create, update, and delete saved keyword lists via API.

Authentication

All KWFinder endpoints require an API key passed as the x-access-token header. See Authentication for setup instructions.

Rate limits and credits

Each keyword lookup counts against your Keyword lookups limit. Duplicate requests within 24 hours are not counted. Use the Get limits endpoint to check remaining credits programmatically.
