Analyzes a URL string for phishing indicators such as homoglyphs, IDN look-alikes, brand tokens in subdomains, IP-literal hosts, @-tricks, excessive length/hyphens/depth, high-abuse TLDs, punycode, and non-standard ports — without making any network request to the URL.

How this service works
Score a URL for phishing patterns: homoglyph/IDN look-alikes, brand tokens in subdomains, IP-literal hosts, @-tricks, excessive length/hyphens/depth, high-abuse TLDs, punycode and non-standard ports. Pure analysis of the string itself — the pre-click check for links from emails, QR codes or chat. Use this when an agent needs to risk-score a URL before clicking or calling it.
Output
Returns a phishing risk score for the submitted URL along with a breakdown of triggered heuristic flags — such as homoglyph/IDN detection, brand token abuse in subdomains, IP-literal host usage, @-trick patterns, excessive URL length, hyphen/depth counts, high-abuse TLD classification, punycode presence, and non-standard port usage — all derived purely from static string analysis without fetching the URL.
Example use cases
Email link safety check
“I just got an email from 'support@amaz0n-account-secure.com' with a link to http://192.168.1.1/login?redirect=@evil.com — can you score that URL for phishing signals before I open it?”
QR code link vetting
“Someone shared a QR code at a conference and it resolves to https://xn--pypal-4ve.com/signin — can you run a phishing heuristic check on that URL and tell me what red flags it has?”
Agent pre-call URL guard
“Before my workflow calls this webhook URL I found — http://free-gift--win--now.tk/claim?token=abc123 — can you analyze it for phishing patterns like high-abuse TLDs, excessive hyphens, or IP tricks?”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/security/phishing-heuristics?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, zero-side-effect, pre-click phishing risk check based purely on URL string structure — especially useful in agentic pipelines before following links from emails, QR codes, or chat messages. Unlike reputation-based or live-fetch checkers, this endpoint makes no network request to the target URL, making it safe and fast for high-volume screening. Prefer this over full web-fetch URL checkers when you only have the URL string and need an instant structural risk signal.
Side effects
- Missing or empty url query parameter returns a validation error
- Malformed or non-string input may return a 400 bad request
- Very long URLs may be truncated or rejected
- The service only performs static string analysis — it cannot detect phishing via page content or reputation data
- Non-HTTP URL schemes (e.g. ftp://, mailto:) may not be fully analyzed
