## 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-stack-detector-60a44f6c
```

Example prompt: Can you tell me what CMS, server, and CDN technologies are powering https://example.com? I want to know their full tech stack.

## When to prefer this

Choose this endpoint when you need programmatic technology fingerprinting of a website on a pay-per-call basis without a subscription, especially in agentic workflows where you need CMS, CDN, and server software identification in a single lightweight call. Prefer it over full web-scraping pipelines when you only need stack detection, not page content.

## Known failure modes

- URL is unreachable or returns non-200 status — partial results or error returned
- Website uses heavy obfuscation or anti-fingerprinting measures — technologies may not be detected
- Missing or malformed 'url' query parameter — request rejected
- Private/intranet URLs not accessible from the worker — timeout or connection error
- Some technologies detected with low confidence may produce false positives in the evidence list

## How this service works

Pay-per-call domain, email and website intelligence for AI agents (x402, USDC on Base). Free demos under /demo/<endpoint>.

## Output

A JSON object containing the queried URL, detected server software, HTTP status code, CMS/generator name and version, and an array of identified technologies each with their name, category (e.g. CMS, CDN, framework), and the evidence strings (HTML patterns, headers) used to detect them.
