# URL Safety API – Phishing & Domain Risk Scorer

> URL Safety API – Phishing & Domain Risk Scorer is a paid API for AI agents from safe.cyberwarex.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-10).

Scores a URL or domain for phishing risk using keyless deterministic heuristics (typosquatting, homoglyphs, punycode, suspicious TLDs, raw-IP hosts, deep subdomains, credentials-in-URL) plus RDAP domain-age lookup, returning a 0–100 risk score and a SAFE/SUSPICIOUS/DANGEROUS verdict.

## 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 url-safety-api-phishing-domain-risk-scorer-84d9fae5
```

Example prompt: Before I open it, can you check if this link is safe — specifically score it for phishing risk: https://secure-paypa1-login.com/verify?user=me

## When to prefer this

Choose this endpoint when an AI agent needs to evaluate an untrusted URL or domain before accessing it, sharing it, or acting on it — especially in phishing-prone contexts like email triage, link preview, user-submitted content moderation, or automated browser agents. Its keyless, deterministic heuristics make it fast and privacy-friendly (no API key required), and the RDAP domain-age check adds signal unavailable from pure heuristics. Prefer it over full-crawl or sandboxed-browsing approaches when you need a lightweight, sub-second risk verdict without fetching the page.

## Known failure modes

- Domain does not resolve — resolves field will be false, DNS records will be empty
- RDAP/WHOIS unavailable for certain TLDs — domain age check may be missing or null
- Newly registered domains may lack RDAP data, reducing scoring accuracy
- Malformed or missing 'domain' query parameter returns an error
- Private/reserved IP ranges passed as host may return minimal data
- Rate limiting or payment failure (x402) returns 402 Payment Required

## How this service works

Pay-per-call URL / phishing safety check for AI agents: score a link for phishing risk from keyless deterministic heuristics (typosquat/homoglyph, punycode, credentials-in-URL, raw-IP host, suspicious TLD, deep subdomains) plus a best-effort RDAP domain-age check. Returns a 0-100 risk score + SAFE/SUSPICIOUS/DANGEROUS verdict.

## Output

Returns a JSON object containing: a 0–100 phishing risk score and a SAFE/SUSPICIOUS/DANGEROUS verdict; the queried host and registrable domain; DNS records (A, AAAA, MX, NS, TXT); WHOIS/RDAP data including creation date, expiry, age in days, registrar, nameservers, and transfer statuses; whether the domain resolves; and whether it has MX records (indicating active mail infrastructure).
