Example prompt: Can you fingerprint the tech stack on stripe.com and tell me what CMS, frameworks, analytics tools, and CDN they're using based on public signals?

## When to prefer this

Choose this endpoint when you need to identify the technology stack of any public website without requiring access to its source code or server. It is well-suited for competitive intelligence, lead enrichment, pre-engagement technical audits, and SEO tooling. Prefer it over manual inspection or browser extensions when you need programmatic, structured results at scale via an API call.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error or empty result
- Private/intranet URLs cannot be fingerprinted from public signals
- Heavily obfuscated or minimal sites may return few or no detected technologies
- Invalid or malformed URL input returns a validation error
- Rate limiting or timeout if the target site is slow to respond

## How this service works

Identify frameworks, analytics, CDNs, servers, and other website technologies from public response signals.

## Output

Returns a structured list of detected technologies for the given website URL, categorized by type (e.g. CMS, JavaScript framework, CDN, analytics, advertising), detected from publicly observable signals such as HTTP headers, HTML markup, and script sources.
