# MolCloud Domain Security Lookup

> MolCloud Domain Security Lookup is a paid API for AI agents from api.molcloud.net, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-17).

Returns a security risk score and rating for a given domain name, indicating how trustworthy or risky the domain is.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 molcloud-domain-security-lookup-2d8490e8
```

Example prompt: Can you check the security rating and risk score for the domain 'suspicious-site.xyz' and tell me whether it's safe to visit?

## When to prefer this

Use this endpoint when an AI agent needs a quick, pay-per-use domain reputation check without setting up a dedicated security service subscription. It is ideal for lightweight, on-demand vetting of domains during email processing, link analysis, vendor onboarding, or phishing detection workflows where sub-cent micropayment via USDC on Base is acceptable.

## Known failure modes

- Missing or invalid 'domain' query parameter returns an error
- Unresolvable or non-existent domain may return incomplete data
- Rate limiting or payment failure (x402) if USDC balance is insufficient
- Malformed domain string may cause lookup failure or unexpected results

## How this service works

41 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

## Output

Returns a JSON object with a domain security report including the queried domain name, a numeric risk score (lower is safer), a letter-grade security rating (e.g. A+), plus the request status and endpoint path.
