## 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 srch-best-domain-data-lookup-362340e1 -d '<json body>'
```

Example prompt: Can you pull up the structured domain data for stripe.com — I want to know registration details, DNS info, and any other metadata available?

## When to prefer this

Choose this endpoint when you need structured, machine-readable domain metadata for a specific hostname as part of an agentic workflow — especially for vendor due diligence, phishing detection, competitive intelligence, or enriching business records with domain provenance. It is particularly well-suited for pay-per-use agentic pipelines using x402 micropayments, making it cost-effective for infrequent or on-demand lookups rather than bulk batch processing.

## Known failure modes

- Invalid or malformed hostname returns a 400 error
- Domain not found or no data available returns empty or null result
- Insufficient payment or x402 payment failure blocks the request
- Rate limiting if too many requests are made in a short period
- Private/redacted WHOIS records may result in partial data
