## 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 hosaka-domain-lookup-4df2a023 -d '<json body>'
```

Example prompt: Can you look up stripe.com and tell me how old the domain is, who their registrar and mail provider are, whether they have DMARC set up, and how many third-party vendors you can detect?

## When to prefer this

Choose this endpoint when you need a quick, no-signup company infrastructure snapshot from just a domain name — especially when you want registrar, mail/DNS provider, DMARC, HTTPS, and vendor exposure all in one call without stitching together multiple DNS/WHOIS APIs. Ideal for due diligence, sales intelligence, or security screening workflows where speed and simplicity matter more than exhaustive detail.

## Known failure modes

- Domain not found or unresolvable — lookup returns no data or an error
- Invalid domain format provided — API may reject with a validation error
- Very new or private domains may return minimal data (no age, unknown registrar)
- Third-party vendor count may be zero or undercount if the company uses few external services
- DMARC and HTTPS checks may time out for slow-responding domains

## How this service works

Company data for AI agents, paid per call in USDC. Reads a company's own DNS to find every third-party vendor it can be proven to use, and returns the record proving each one.

## Output

A structured profile of the queried company domain including: domain age, registrar name, mail provider, DNS provider, DMARC policy status, HTTPS availability, and a count of detectable third-party vendors — all returned in a single response with no authentication required.
