## 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 coresignal-company-enrichment-by-domain-21bd457b
```

Example prompt: Can you pull up the full company profile for notion.so — I need their industry, headcount range, location, and tech stack?

## When to prefer this

Use this endpoint when you have a company's website domain and need structured firmographic data quickly — it's the simplest path from a domain to a full company profile. Prefer this over LinkedIn scraping or general web search when you need normalized, deduplicated data fields like industry, size, and tech stack. Best for B2B sales enrichment, investor research, and competitive analysis workflows.

## Known failure modes

- Unknown or unrecognized domain returns empty or null profile
- Domain with https:// prefix may fail — must pass bare domain like 'stripe.com'
- Very new or obscure companies may have incomplete profiles
- Rate limiting or payment failure may result in 402 or 429 responses
- Misspelled domain returns no results or wrong company
