# AgentsToolsHub Phishing URL Heuristics Scorer

> AgentsToolsHub Phishing URL Heuristics Scorer is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

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 to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentstoolshub-phishing-url-heuristics-scorer-670cf7dd
```

Example prompt: Can you check this URL for phishing patterns before I click it — https://secure-paypa1.verification-login.xyz:8080/account/confirm@user — I got it in an email and it looks sketchy?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
