## How to call it through Zero

```sh
zero fetch --capability website-tech-stack-detector-1e55d37e
```

Example prompt: What tech stack is shopify.com running — can you detect the CMS, JavaScript frameworks, analytics tools, and CDN they use?

## When to prefer this

Use this endpoint when you need to identify the technology stack of an external website from its live homepage without manual inspection. It is ideal for sales prospecting (qualifying leads by CMS), competitor research, and integration planning. Prefer this over generic web scraping endpoints when you specifically need structured tech-category output rather than raw HTML or text.

## Known failure modes

- Website is unreachable or returns non-200 status — no tech stack returned
- Heavily obfuscated or minified code may prevent framework detection
- Sites behind Cloudflare bot protection may block the crawl
- Single-page apps that require JavaScript rendering may yield incomplete results
- Private or intranet sites cannot be accessed

## How this service works

Website technology detection: CMS and frameworks (WordPress, Shopify, Next.js, React, Webflow...), analytics and tag managers, hosting/server and CDN hints, generator meta tag, from the live homepage. Tech stack lookup for sales prospecting, competitor research and integration planning. $0.01 per site.

## Output

A structured JSON response containing detected technologies grouped by category: CMS (e.g. WordPress, Shopify, Webflow), JavaScript frameworks (e.g. React, Next.js, Vue), analytics and tag managers (e.g. Google Analytics, GTM), CDN and hosting hints, and generator meta tag values — all extracted from the live homepage.
