## 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 ipv4-fr-company-intelligence-api-1bb2c222
```

Example prompt: Can you pull up everything you know about the company behind stripe.com — their industry, tech stack, email and DNS providers, products, and social links?

## When to prefer this

Choose this endpoint when you need rich, multi-dimensional company intelligence from a single domain lookup — especially when you want technology stack, DNS/email provider, industry, business model, and social profiles in one call. Prefer it over raw WHOIS or DNS lookups when you need business context rather than just technical records, and over general web scrapers when you want structured, pre-parsed company data without writing your own extraction logic.

## Known failure modes

- Domain not found or unresolvable — empty or null fields returned
- Domain has no crawlable content — minimal data returned
- Rate limit exceeded on free tier — HTTP 429 error
- Invalid domain format in path parameter — HTTP 400 error
- Payment not provided or insufficient — HTTP 402 error
- Cached result may be stale if domain recently changed
