SERPChecker

SERPChecker is Mangools' SERP analysis tool. The API gives you access to live and cached SERP snapshots for any keyword, along with per-result SEO metrics (DA, PA, backlinks, Facebook shares) and URL-level authority signals — the same data that powers the SERPChecker app.

What you can do

• Fetch SERPs — retrieve ranked results for a keyword and location, including SERP features.
• Analyze URLs — get SEO metrics for any URL: domain authority, page authority, backlink count, and more.
• Reset cached SERPs — force a fresh SERP fetch when you need up-to-date results.
• View SERP snapshots — retrieve a historical snapshot of a SERP by ID.
• Track request usage — monitor how many SERP requests you have remaining.

Authentication

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