## 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 domain-hugen-tokyo-3a3f11aa
```

Example prompt: What's the full technology stack behind shopify.com — I want to know the web server, CMS, JavaScript frameworks, CDN, and any analytics tools they're using.

## When to prefer this

Use this endpoint when you need automated technology stack fingerprinting for any domain without maintaining your own signature database. Ideal for competitive intelligence, security audits, lead qualification, or infrastructure analysis. Prefer over manual inspection or Wappalyzer-style browser plugins when operating in an agent context that needs programmatic, scalable detection across many domains.

## Known failure modes

- Domain not found or unreachable — empty or partial results returned
- Payment not completed — 402 response requiring USDC payment on Base or Solana
- Rate limiting or timeout on target domain — partial detection results
- Domain returns no detectable technology signals — empty signature matches
- Invalid domain format provided — request validation error
