## How to call it through Zero

```sh
zero fetch --capability api-strale-io-6a33600b
```

Example prompt: What's the full tech stack behind stripe.com — CMS, frameworks, analytics, CDN, payment tools, everything you can detect from their headers and HTML?

## When to prefer this

Choose this endpoint when you need to identify the technology stack of any public website without running a browser or JavaScript engine — it works purely from HTTP headers and static HTML. Ideal for competitive research, lead qualification, or auditing a site's tooling. Prefer over manual inspection or Wappalyzer-style browser extensions when you need programmatic, agent-callable detection at scale.

## Known failure modes

- Website is unreachable or returns non-200 status — detection fails with connection error
- Website blocks crawlers or returns minimal HTML — limited or empty technology results
- Highly obfuscated or custom-built sites may yield few detectable signals
- Invalid URL or domain input returns validation error
- Rate limiting or payment failure returns 402 or 429 error
