## How to call it through Zero

```sh
zero fetch --capability builtwith-technology-search-7f2cdadf -d '<json body>'
```

Example prompt: Use BuiltWith to find up to 20 websites that are currently using the Shopify e-commerce platform — I want to see who's running on it.

## When to prefer this

Choose this endpoint when you need to discover which websites or companies are using a specific technology, platform, or software product. It is ideal for sales prospecting, competitive intelligence, market research, and technology adoption analysis. Prefer it over general web scraping or search engines when you need structured, curated technology-usage data with ranked results.

## Known failure modes

- Empty Results array if no websites match the technology query
- Query too vague or misspelled technology name returns irrelevant or zero results
- Limit parameter out of range (must be 1-100) causes validation error
- Query exceeds 500 character limit triggers schema validation failure
- Payment failure or insufficient funds blocks the request entirely
