Check a website URL for safety. Analyzes domain age, SSL certificate, redirect chains, brand impersonation, Google Web Risk, URLhaus, ThreatFox, and community reports. Returns risk score and detailed signals.
AI agents call check_url to retrieve information from ScamVerify without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query against threat intelligence records to assess URL safety. It retrieves and analyzes existing data without creating, modifying, deleting, or executing any operations. The analysis is purely informational—the tool returns risk scores and signals but does not take actions on the URL or trigger external operations.
From the tool's definition Tool name 'check_url' and description states it 'Analyzes' and 'Returns risk score and detailed signals' with no modification, deletion, or execution capabilities.
