## 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 dopaminedesk-tech-stack-lookup-40ebe5ff
```

Example prompt: Can you look up the tech stack for stripe.com and tell me what frontend framework, backend, and hosting they use?

## When to prefer this

Use this endpoint when you need a structured, categorized breakdown of a website's technology stack — including frontend, backend, hosting, analytics, and marketing layers — with a confidence score. Prefer it for competitive intelligence, sales prospecting enrichment, or due diligence workflows where you need machine-readable tech profiles per domain. It is distinct from raw web scraping because it interprets detected signals into named technology categories rather than returning raw HTML or headers.

## Known failure modes

- Unknown or very new domain returns empty technology arrays with low confidence score
- Private or obscured tech stacks (e.g. behind Cloudflare proxies) may yield incomplete or inaccurate results
- Invalid domain format returns an input validation error
- Domain with no public web presence returns minimal data
- Payment failure via x402 returns HTTP 402 and the call is not processed

## How this service works

Fetch a public website with private-network blocking and report transparent heuristic technology signatures from markup and headers.

## Output

A JSON object containing the queried domain, categorized arrays of detected technologies (frontend, backend, hosting, analytics, marketing), any additional technology categories found, and a numeric confidence score (0–1) indicating how reliable the detection is.
