## When to prefer this

Use this endpoint when you need a comprehensive, multi-signal tech stack fingerprint of any publicly accessible domain — covering frontend, backend, analytics, CDN, hosting, and CMS in a single call. Prefer this over manual inspection or generic scraping when you need structured, categorized output across many tech dimensions simultaneously, such as for competitive intelligence, vendor research, or sales prospecting.
