# ClearCheck Domain Trust Checker

> ClearCheck Domain Trust Checker is a paid API for AI agents from loonie-toll.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

Evaluates a domain, URL, or email address for trustworthiness using domain age, DNS records, HTTPS certificate, nameserver status, and email authentication, returning a PASS / CAUTION / BLOCK verdict with reasons.

## 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 clearcheck-domain-trust-checker-43131638
```

Example prompt: Can you run a trust check on suspicioussite.xyz and tell me if it's safe — I want to know the verdict, how old the domain is, and whether it has proper DNS and HTTPS?

## When to prefer this

Use this endpoint when you need a quick, multi-signal trust verdict on an unknown domain, URL, or email sender before taking action — particularly when you care about domain age, DNS hygiene, HTTPS validity, and email authentication (SPF/DMARC) in a single call. Prefer it over raw WHOIS lookups when you want a structured PASS/CAUTION/BLOCK decision rather than raw data, and over general reputation databases when you need real-time DNS and certificate checks rather than historical blacklist data.

## Known failure modes

- Unresolvable or non-existent domain returns missing DNS fields
- Very new domains may lack registration data, lowering score
- Private WHOIS may prevent retrieval of registrar/creation date
- Domain for-sale nameservers may trigger BLOCK even for legitimately purchased domains
- Temporary DNS propagation issues may cause transient failures
- Network timeout if the target domain's DNS is slow to respond

## How this service works

Is this domain safe to trust? PASS / CAUTION / BLOCK from domain age, for-sale name servers, DNS, HTTPS and email auth.

## Output

Returns a JSON object containing a verdict (PASS, CAUTION, or BLOCK), a numeric trust score, an array of human-readable reasons, DNS records (A, MX, NS, SPF, DMARC policy), HTTPS certificate details (issuer, days left, hostname match), domain registration info (registrar, creation date, expiry date, status), and a disclaimer with a timestamp.
