## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability builtwith-company-to-url-46163a36 -d '<json body>'
```

Example prompt: What are the top 5 domains associated with the company Stripe? I want to see their websites, social profiles, and rankings from BuiltWith.

## When to prefer this

Use this endpoint when you have a company name and need to discover its associated web domains, especially for competitive intelligence, lead enrichment, or verifying a company's web presence. Prefer this over a general web search when you need structured, ranked domain data with social profiles and location metadata from BuiltWith's 100M+ website database.

## Known failure modes

- Company name not found — returns empty data array
- Ambiguous company name matches many unrelated domains — low-quality results with generic names
- Result limit too high — may return many parked or irrelevant domains
- Network timeout or API unavailability — HTTP 5xx error
- Missing required COMPANY parameter — request validation error

## How this service works

Discover domains owned by a company. Returns domains with spend, rank, location, and social links.

## Output

Returns a list of domain records associated with the company, each including the domain name, company name, city, state, country, postcode, social media profile URLs (Twitter, Facebook, LinkedIn), PageRank, BuiltWithRank, ad spend, and whether the domain is parked.
