# /securityheaders/scans

> Scan a site's HTTP response security headers and grade them via SecurityHeaders.com

**Price:** 1 credit

**💡 AI Hint:** Scan a website's HTTP response security headers and get its SecurityHeaders.com grade (A+ down to F). Returns the grade, the final scanned URL and resolved IP address, the list of present security headers, the missing security headers with recommendations, every raw HTTP response header with its actual value, upcoming/recommended headers, and additional notes. Accepts a full URL or a bare domain. Useful for security posture, attack-surface, and compliance reconnaissance of any domain.

**⚠️ Common errors:** 412: The target site could not be scanned (unreachable or rejected)
