Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 netzhandwerker-tech-detect-7d143227 -d '<json body>'
```

Example prompt: Can you detect what technologies and frameworks are used on https://example.com — and use headless Chrome rendering to make sure you catch any JavaScript-loaded tools too?

## When to prefer this

Choose this endpoint when you need to detect the technology stack of a specific website, especially when you want optional headless Chrome rendering to catch dynamically loaded JavaScript frameworks and tools. Prefer this over generic web scrapers when the goal is technology fingerprinting rather than content extraction.

## Known failure modes

- URL is unreachable or returns non-200 status — detection fails with an error
- Heavily bot-protected sites may block the crawler and return incomplete or no results
- Without render:true, single-page apps may not expose their full tech stack
- Very new or obscure technologies may not be in the detection fingerprint database
- Malformed URL input causes a validation error

## How this service works

x402-Werkzeuge für autonome Agenten.

## Output

Returns a structured breakdown of the detected technologies powering the target website, potentially including CMS, frontend frameworks, JavaScript libraries, analytics platforms, CDN/hosting providers, server software, and other detectable stack components. When headless Chrome rendering is enabled, dynamically injected tools and client-side frameworks are also detected.
