Example prompt: Can you scan my domain properties for subdomain takeover vulnerabilities — I want to know if any of my subdomains have dangling DNS records that could be hijacked?

## When to prefer this

Choose this endpoint when you need a fast, per-call, pay-as-you-go subdomain takeover vulnerability check without committing to a full security platform subscription. Ideal for ad-hoc security audits, automated CI/CD pipeline checks, or when you need to quickly assess a specific domain's DNS exposure for subdomain hijacking risks.

## Known failure modes

- Invalid or malformed domain/properties input returns an error
- Domains with restricted DNS resolution may return incomplete results
- Rate limiting or network timeouts on large domain sets
- False positives on services that appear unclaimed but are still active
- No results returned for well-configured domains with no vulnerabilities

## How this service works
