## How to call it through Zero

```sh
zero fetch --capability builtwith-product-da38d785 -d '<json body>'
```

Example prompt: Search BuiltWith's product database for technologies related to 'artificial intelligence' and show me the first 50 results.

## When to prefer this

Use this endpoint when you need to discover or look up specific technology product names within BuiltWith's catalog before using other endpoints like Domain Lookup or Technology Lists. It is the right starting point when you have a product name or keyword and want to confirm how BuiltWith identifies or categorizes that technology.

## Known failure modes

- Missing required QUERY parameter returns validation error
- Empty or overly generic query returns large unfiltered result set
- Invalid PAGE or LIMIT values may return default pagination or error
- No results found for highly specific or misspelled product names
- Rate limiting or authentication failure if credentials are invalid

## How this service works

Find websites selling specific products. Returns shops with product titles, URLs, prices, and indexed dates.

## Output

A paginated list of technology products in BuiltWith's database that match the search query, including product names and related metadata useful for identifying which tech products to investigate further via other BuiltWith endpoints.
