## How to call it through Zero

```sh
zero fetch --capability builtwith-trends-1ef9de6f -d '<json body>'
```

Example prompt: How many live websites are currently using Shopify, and what categories does it fall under? Pull the BuiltWith trend data for it.

## When to prefer this

Use this endpoint when you need quantitative adoption metrics for a specific named technology — how many sites use it, whether it's growing or declining, and how it's categorized. Prefer this over domain-level lookups (which tell you what a single site uses) when you want population-level statistics about a technology's reach. Best for market research, competitive analysis, and understanding a technology's footprint across the web.

## Known failure modes

- Unknown or misspelled technology name returns no data or empty result
- Technology name with ambiguous casing may not match — exact name may be required
- Premium technologies may require elevated API access
- Network timeout for rarely-queried technologies
- Invalid or missing TECH field returns validation error
