Fast Check
Quickly assesses URL safety without performing a full scan. Returns malicious score and classification (SAFE, MALICIOUS, or UNRATED) based on existing intelligence and heuristics. Ideal for real-time URL validation.

Successful Response
Numerical score (0-1) indicating likelihood of malicious intent. Higher values indicate greater risk.
The URL that was checked.
URL classification: SAFE (verified benign), MALICIOUS (threat detected), UNRATED (insufficient data).
Available options:
SAFE, MALICIOUS, UNRATED Scan ID associated with the checked URL. This attribute is omitted if the URL is not present in the system.
