Example prompt: Can you look up the full tech stack, email security setup (SPF, DKIM, DMARC), and domain age for stripe.com in one shot?

## When to prefer this

Choose this endpoint when you need technology stack detection AND email security posture AND domain age all in one call without stitching together multiple DNS, RDAP, and web-scraping APIs. It is especially useful for security triage, vendor due diligence, lead enrichment, and competitive intelligence workflows where a single domain lookup must yield comprehensive infrastructure intelligence with evidence included.

## Known failure modes

- Invalid or non-existent domain returns an error or empty result
- Rate limiting if more than 10 domains are submitted in one call
- DNS lookup timeout for domains with slow nameservers
- Partial results if a domain blocks certain DNS record types
- RDAP data unavailable for certain TLDs or privacy-shielded registrations
