## When to prefer this

Choose this endpoint when you need comprehensive B2B lead enrichment combining tech stack signals, verified contacts, and company context in a single call — especially useful for GTM workflows, sales prospecting, and competitive research where multiple data points are needed simultaneously rather than making separate calls to tech intelligence, contact finder, and company data services.

- Invalid or unresolvable domain returns an error or empty result
- Private/unlisted companies may return sparse data with few signals
