## 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 agentbit-web-tech-stack-detector-fca137fb -d '<json body>'

Example prompt: Can you scan stripe.com and tell me what CMS, frameworks, CDN, analytics, and payment tools they're using — with evidence?

## When to prefer this

Choose this endpoint when you need a BuiltWith-style technology fingerprint for any public website — including CMS, frontend frameworks, CDN/hosting, analytics, server software, and payment providers — all in one call with evidence. Prefer it over manual inspection or browser DevTools when you need programmatic, agent-accessible results at scale or in automated workflows.

## Known failure modes

- URL is unreachable or returns a non-2xx response — detection fails or returns empty results
- Website uses heavy anti-bot protections (Cloudflare challenge, IP blocking) — may return incomplete or no data
- Private/intranet URLs cannot be crawled — returns an error
- Dynamically rendered SPAs may obscure some server-side technology signals
- Malformed URL input causes a validation error

## How this service works

Detect the technologies behind any website (BuiltWith-style): CMS, frameworks, CDN/hosting, analytics, server, payments. Evidence included.

## Output

A structured breakdown of the detected technologies across categories such as CMS, JavaScript frameworks, CDN/hosting, analytics platforms, server software, and payment processors, each accompanied by evidence (e.g., HTTP headers, HTML signals, script URLs) that supports the detection.
