Example prompt: Can you scan https://shopify.com and tell me what technologies and frameworks it's built with?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call technology fingerprint of any public website without managing API keys or subscriptions. It is well-suited for competitive research, sales intelligence, or developer audits where you need to identify frameworks, CMS platforms, analytics tools, and hosting providers from a single URL scan.

## Known failure modes

- Invalid or unreachable URL returns an error or empty technologies array
- Private/intranet URLs are not accessible and return no results
- Rate-limited or bot-protected sites may yield incomplete detection
- Malformed URL input (missing scheme) may cause a parsing error
- Payment failure results in HTTP 402 before the scan is performed
