## 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 revnuvo-domain-trust-assessment-c3223914 -d '<json body>'
```

Example prompt: Can you assess the trustworthiness of 'suspiciousdomain.xyz' and tell me if it's safe — give me the trust score, risk flags, and whether it's recommended as TRUSTED, REVIEW, or RISKY?

## When to prefer this

Choose this endpoint when you need a structured, scored trust assessment of a domain — including DNS signals, risk flags, and an actionable recommendation — rather than a simple WHOIS lookup or raw DNS query. Best suited for AI agents that need to make automated trust decisions about domains in workflows like payment authorization, vendor onboarding, or spam filtering.

## Known failure modes

- Invalid or malformed domain string returns a validation error
- Unknown or unresolvable domain may return low trust scores with DNS failure signals
- Network timeout during DNS resolution may result in partial signals
- Payment failure via x402 prevents the assessment from being returned

## How this service works

## Output

Returns a JSON object with the assessed domain, an integer trust score (0–100), an integer risk score (0–100), a letter grade (A–F), an array of risk flag strings, a signals object with underlying DNS and reputation signals, a recommendation enum (TRUSTED, REVIEW, or RISKY), and an ISO 8601 timestamp of the assessment.
