zero fetch --capability contactout-domain-enrichment-88051318 -d '<json body>'
```

Example prompt: Can you look up company information for these domains: stripe.com, twilio.com, and sendgrid.com? I need to know what companies are behind them.

## When to prefer this

Choose this endpoint when you need to enrich company domains with firmographic data, especially in B2B sales, marketing automation, or CRM workflows. It is particularly useful when you have a list of company websites and need to identify the organizations behind them. Prefer this over general web scraping when you want structured company data rather than raw HTML.

## Known failure modes

- Unknown or unrecognized domain returns empty or null result
- Invalid domain format causes validation error
- Domain belongs to a personal site or individual, not a company
- Rate limiting or quota exhaustion returns error
