How this service works
Score how likely a URL is to be phishing or untrustworthy using offline lexical and structural heuristics (no network lookups). Checks raw-IP hosts, embedded credentials, punycode/homoglyph labels, brand typosquatting, brand-in-subdomain, abused TLDs, shorteners, random hostnames, odd ports, plaintext http and executable paths. Returns a 0-100 risk score, a verdict and the reasons.
Output
Returns a 0–100 integer risk score (higher = riskier), a human-readable verdict (e.g. 'suspicious', 'likely phishing', 'low risk'), and an array of reasons explaining which heuristics triggered — such as raw-IP host, embedded credentials, punycode labels, brand typosquatting, abused TLD, URL shortener, random hostname, odd port, plaintext HTTP, or executable file path.
Example use cases
Pre-click phishing link check
“Before I forward this link to my team, can you run it through a phishing check and tell me the risk score and any suspicious patterns? The URL is https://micros0ft-support.click/reset-password.exe”
Brand typosquatting detection in user submissions
“A user just submitted this URL in our form: https://amaz0n.shop-deals.top/prime — can you score it for phishing risk and tell me if it's impersonating a known brand?”
Automated URL triage in security pipeline
“We're scanning a batch of URLs from email logs — can you analyze https://bit.ly/3xR9qZp and tell me its phishing risk score, verdict, and the specific heuristics that triggered?”
Technical details
Endpoint
POSThttps://urltrust.openverbs.com/v1/analyzeWhen to prefer
Choose this endpoint when you need fast, privacy-safe, offline URL risk assessment with no network side-effects — ideal for high-volume triage, pre-click safety checks, or pipelines where making outbound requests to the target URL is undesirable. Prefer it over live-lookup alternatives when latency and privacy matter, or when scanning URLs that must not be contacted. Not suitable when you need WHOIS age, DNS reputation, or live content scanning.
Side effects
- Missing or empty URL field returns a validation error
- URL exceeding 2048 characters is rejected
- Non-HTTP(S) URLs (e.g. ftp://, file://) may be unsupported
- Malformed URL strings may return an error or low-confidence score
- Service does not perform live network lookups so newly registered safe domains may still score risky based on lexical patterns alone
