## 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 hergert-synthora-domain-risk-classifier-90815f11 -d '<json body>'
```

Example prompt: Can you run a domain risk check on 'malware-example.ru' and tell me whether it comes back CLEAN, SUSPICIOUS, or MALICIOUS based on the multi-source scoring?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, multi-source risk verdict for a specific domain or IP and want a single consolidated CLEAN/SUSPICIOUS/MALICIOUS label rather than raw feed data. Particularly useful for pre-connection vetting, phishing detection, and automated SOC triage where a simple actionable classification is needed without building your own threat intel aggregation pipeline.

## Known failure modes

- Invalid or malformed domain/IP input returns an error result
- Domain not found in any of the six sources may return ambiguous or low-confidence verdict
- Network timeout when querying upstream threat feeds may delay or fail the response
- Unparseable input string (e.g. free text instead of a domain/IP) returns a validation error
- Payment not processed correctly via x402 results in 402 status and no verdict
