## 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 54ch10-dns-reputation-lookup-0e6d73c2
```

Example prompt: Can you run a DNS reputation check on 'suspicious-airdrop.xyz' and tell me if it's been flagged for phishing or anything sketchy before I click on it?

## When to prefer this

Use this endpoint when an agent needs a quick, low-cost DNS resolution plus basic phishing/scam reputation check on a domain before a user interacts with a URL, DeFi protocol, or web service. Prefer this over generic DNS tools when you specifically need risk-flag context (phishing, honeypot, scam indicators) alongside resolution results. Best suited for pre-interaction safety screening in crypto, Web3, or general browsing contexts.

## Known failure modes

- Domain not found or unresolvable — ok may be false with empty A records
- Domain provided in invalid format — may return validation error
- No flags returned even for risky domains — heuristic scoring is imperfect and may miss novel threats
- Rate limits or payment failures — endpoint requires x402 micropayment of $0.002 USDC per call
- Empty flags array does not guarantee safety — must verify independently

## How this service works

54ch10: pre-interact URL check. Paste a link, get brief + domain + page. Taste /v1/open/free. 80 calls for $1. Wire in 30s. Analytics-only tooling. Not financial advice.

## Output

Returns an object containing DNS A records for the domain, an 'ok' boolean indicating successful resolution, a 'tier' field (e.g. 'x402'), a 'flags' array listing any detected risk signals (phishing, scam, honeypot, etc.), the queried domain name, and a disclaimer that results are informational heuristics only.
