## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability website-technology-detection-b9c02d40
```

Example prompt: Can you check what technologies acmecorp.com is running — I want to know their CMS, JavaScript framework, CDN, and any analytics or payment tools they're using?

## When to prefer this

Choose this endpoint when you need to identify the technology stack of any public website for purposes like lead qualification, sales prospecting, or competitive research. It is purpose-built for tech fingerprinting from HTTP headers and HTML, covering a wide range of categories (CMS, frameworks, CDN, analytics, payments, chat). Prefer this over general web scraping endpoints when the goal is specifically technology identification rather than content extraction.

## Known failure modes

- URL is unreachable or returns an error — detection fails with no results
- Website uses heavy obfuscation or server-side rendering that hides technology signals — partial or empty results
- Domain resolves but returns a parked or redirect page — inaccurate or minimal detection
- Invalid or malformed URL input — request rejected with validation error
- Rate limiting or anti-bot protections on the target domain — may limit header/HTML retrieval

## How this service works

Detect the technologies a website uses from its headers and HTML: CMS (WordPress, Shopify, Webflow), frameworks (Next.js, React, Vue), CDN and hosting (Cloudflare, Vercel), analytics, chat, payments. Use for lead qualification, sales prospecting or competitor research.

## Output

A structured list of detected technologies categorized by type (CMS, JavaScript framework, CDN/hosting, analytics, chat, payments), identified from the target website's HTTP response headers and HTML source. Each detected technology is typically named with its product identifier (e.g. WordPress, Next.js, Cloudflare, Google Analytics).
