> AgentRXI Link Safety Check is a paid API for AI agents from agentrxi.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-15).

Checks whether a URL is malware or phishing by querying Cloudflare's DNS blocklist, assessing domain age, detecting brand impersonation, following redirect chains, and returning a safety verdict with a risk score.

## 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 agentrxi-link-safety-check-7ac13c5f
```

Example prompt: Can you check if this link is safe to click — https://bit.ly/3xAb12z — I want to know if it's phishing or malware before I open it.

## When to prefer this

Choose this endpoint when you need a fast, multi-signal URL safety check that combines DNS blocklist lookup, redirect chain analysis, domain age, and brand impersonation detection in a single call. Prefer it over raw DNS lookups when you need a holistic risk score rather than a single signal, especially for shortened URLs or suspicious links in user-generated content.

## Known failure modes

- Invalid or malformed URL returns an error
- URL that times out during redirect chain following may return incomplete results
- Very new domains may have limited age data
- Some shortener services may block automated redirect resolution
- False negatives possible for newly registered malicious domains not yet blocklisted

## How this service works

Link safety check: is this URL malware or phishing? Checks Cloudflare's security DNS blocklist, domain age, look-alike and brand-impersonation tricks, shorteners and the redirect chain, then gives a verdict and risk score.

## Output

Returns a safety verdict (safe/unsafe/suspicious), a numeric risk score, whether the domain is on Cloudflare's security DNS blocklist, domain age, detection of look-alike or brand-impersonation patterns, and the full redirect chain followed from the URL.
