## 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 namewhere-company-name-to-domain-lookup-eeac07fb
```

Example prompt: What's the official website domain for Acme Brick Company? I need the domain with a confidence score of at least 0.7, preferring US results.

## When to prefer this

Use this endpoint when you need to map a company name to its authoritative official domain with explainable confidence evidence. Prefer it over generic web search when you need structured, scored, machine-readable output with a reliability threshold you can tune via minConfidence. It is especially useful for CRM enrichment, B2B lead pipelines, and outreach automation where domain accuracy is critical.

## Known failure modes

- Low confidence match — company name is ambiguous or too generic, confidence falls below minConfidence threshold and status is 'unresolved'
- No match found — company is too obscure or name too abbreviated for resolution
- Ambiguous name — multiple companies share the same name across countries, requiring a country hint
- Rate limiting or payment failure — x402 micropayment not processed correctly
- Invalid input — missing required 'company' query parameter

## How this service works

Company names in, official website domains out. Company name to domain, with the evidence behind every match Try it free in one click, no sign-up.

## Output

Returns the resolved official domain for the company, a confidence score indicating match certainty, the resolution status (e.g. 'resolved' if confidence meets the threshold), and evidence supporting the match. May also handle direct domain, URL, or email verification if those are passed instead of a company name.
