How this service works
Domain reputation & security check
Output
Returns a domain reputation assessment including threat classification, blacklist status, and security intelligence signals indicating whether the domain is safe, suspicious, or malicious
Example use cases
Verify merchant domain before payment
“Check if the domain on this invoice is legitimate before I wire funds — I need to know if it's blacklisted or showing any phishing indicators”
Validate callback URLs for webhooks
“Before I set up webhooks from this service, can you run a security check on their domain to make sure it's not malicious or compromised?”
Detect suspicious email sender domains
“Someone sent me an email claiming to be from our bank but the domain looks off — can you check if that domain has a bad reputation or is known for phishing attacks?”
