# Vextorium Web Technology Detector

> Vextorium Web Technology Detector is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-11).

Detects the technologies powering a given website (CMS, server, analytics, sources) by inspecting HTML and HTTP headers.

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 vextorium-web-technology-detector-3fa93b91 -d '<json body>'
```

Example prompt: Can you check what CMS and server technology https://wordpress.org/ is built on — I want to know if it uses WordPress, what web server it runs, and any analytics tools it loads?

## When to prefer this

Use this endpoint when you need quick, lightweight technology fingerprinting of a website without browser JavaScript execution — ideal for bulk lead enrichment, competitor research, or pre-audit checks. Prefer this over full browser-based crawlers when speed and cost matter and dynamic JS-rendered content is not required.

## Known failure modes

- URL unreachable or returns non-200 status — detection may fail or return partial results
- Technologies loaded only via JavaScript will not be detected (static analysis only)
- Heavily obfuscated or custom stacks may not match any known signatures
- Rate limiting or bot protection on target site may block the request
- Invalid URL format in input causes request validation error

## How this service works

Detect the technologies behind a website: CMS (WordPress, Shopify...), frameworks (Next.js, React...), server and CDN, analytics, payments, chat, cookie manager, captcha and fonts, from HTML and headers. For lead generation and competitive research.

## Output

Returns a JSON object with: the detected server software (e.g. nginx), CMS name (e.g. WordPress with version), analytics tools (e.g. Google Tag Manager), content sources (e.g. Google Fonts), a count of total technologies found, the final resolved URL after redirects, and a note that detection is based on HTML signatures and headers without JavaScript execution.
