## 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 speer-cyber-defense-vendor-risk-assessment-69158c41
```

Example prompt: What's the vendor risk assessment for acme-supplier.com? I need to know if they're safe to onboard as a third-party supplier.

## When to prefer this

Use this endpoint when you need a quick, affordable ($0.01 USDC) cybersecurity vendor risk profile for a specific domain — ideal for third-party supplier due diligence, vendor onboarding checks, or supply chain risk monitoring. Prefer this over generic WHOIS or DNS lookups when you specifically need a security-focused risk summary.

## Known failure modes

- HTTP 503 if security analysis fails (not billed)
- Missing or invalid domain query parameter returns an error
- Domain not found or unresolvable may yield limited results
- Payment failure via x402 blocks access to the paid endpoint
