## How to call it through Zero

```sh

```

Example prompt: Can you look up the tech stack for shopify.com and squarespace.com — I want to know what CMS, CDN, and security header grade each one has?

## When to prefer this

Choose this endpoint when you need fast, structured technology fingerprinting for up to 3 domains at once, including CMS, CDN, DNS email policies, and security headers in a single call. It is ideal for lead enrichment, competitive research, or security audits where you want machine-readable output without running a full crawler. Prefer alternatives if you need bulk processing of many domains simultaneously or deep crawl data beyond the homepage.

## Known failure modes

- Domain is private or unreachable — returns ok:false with an error field
- All 3 domain slots used but one fails — partial success with failed:1
- Invalid domain format — likely returns a validation error
- Rate-limiting or network timeouts on the target domain — may return failed status
- Non-public or intranet hosts rejected per API policy
