## 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 urltrust-tech-stack-profiler-d02976f4 -d '<json body>'
```

Example prompt: Can you look up the technology stack for stripe.com — I want to know what CDN, analytics, CMS, and payment tools they're using, plus their domain rank and country?

## When to prefer this

Use this endpoint when you need a comprehensive, categorized technology fingerprint of a domain — not just a trust score or phishing check. Prefer this over the sibling trust-scoring endpoints when the goal is competitive intelligence, vendor due diligence, lead enrichment, or understanding what third-party services a site depends on. It is especially useful when you need structured, category-grouped tech data (CDN, CMS, analytics, etc.) rather than a single risk signal.

## Known failure modes

- Domain not found in database returns found=false with no technology data
- Invalid or malformed domain (e.g. includes scheme or path) may produce unexpected results
- Domain with very low traffic or newly registered may have no rank or tech data
- Rate limiting or payment failure results in 402 response
- Stale data if domain recently changed its tech stack (last-seen date indicates freshness)

## How this service works

Detect the technology stack a website runs on. Given a domain, returns the software and services it uses (CDN, analytics, frameworks, CMS, payment, hosting, security) grouped by category, plus a domain rank, last-seen date, country and public social links. Unknown domain returns found=false.

## Output

Returns a structured profile of the domain including a 'found' boolean, grouped technology categories (CDN, analytics, CMS, frameworks, payment, hosting, security), global domain rank, country of origin, last-seen date, and any publicly available social media links. If the domain is unknown, returns found=false with no tech data.
