## 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 contactout-domain-enrich-f4a55c2a -d '<json body>'
```

Example prompt: Can you look up the company details for stripe.com — I need to know their industry, employee count, and location for a sales lead I'm working on?

## When to prefer this

Use this endpoint when you have a company domain name and need firmographic enrichment — company size, industry, location, revenue — without a LinkedIn URL or person-level data. Ideal for B2B sales prospecting, lead enrichment pipelines, and CRM data hygiene where you start with just a website domain.

## Known failure modes

- Domain not found in ContactOut database — returns empty or null company record
- Invalid domain format — returns validation error
- Domain resolves to a personal site or non-company entity — returns minimal or no data
- Rate limit exceeded — returns 429 error
- Authentication failure — returns 401 unauthorized

## How this service works

## Output
