## When to prefer this

Use this endpoint when you need a quick, automated fingerprint of a website's technology stack from a single URL without manually inspecting page source or HTTP headers. Ideal for competitive research, lead qualification, pre-sales intelligence, and security audits where knowing the underlying CMS, CDN, analytics, and frameworks is important.

## Known failure modes

- Invalid or malformed URL returns an error response
- Private or unreachable URLs (intranets, localhost) return no data
- Sites with heavy obfuscation or custom setups may return an empty technologies array
- Very slow sites may time out before analysis completes
- Some technologies may be undetectable if headers and scripts are suppressed
