## 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 how-is-company-lookup-71e4ab11 -d '<json body>'
```

Example prompt: Can you look up the company behind stripe.com and tell me what they do, where they're based, what category they're in, and who their DNS and hosting providers are?

## When to prefer this

Use this endpoint when you need a comprehensive, sourced company profile from a single domain name, including business metadata, social links, infrastructure providers, and registration details all in one call. Prefer this over manual WHOIS lookups, LinkedIn searches, or separate DNS queries when you want a unified, confidence-scored company card. Especially useful for sales enrichment, vendor vetting, fraud investigation, or competitive intelligence workflows.

## Known failure modes

- Domain not found or not registered — returns empty or minimal data
- Low confidence scores when insufficient public data exists for the domain
- Domain is too new to have indexed company information
- Rate limiting or payment failure via x402 protocol
- Malformed domain input exceeding 253 characters or containing invalid characters
- Private/redacted WHOIS data limiting registrant enrichment

## How this service works

## Output
