## 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 optix402-x402-marketplace-intelligence-api-service-domain-lookup-eb31448e
```

Example prompt: Pull up the x402 marketplace intelligence for the domain 'example.com' — I want to see its market stats, buyer activity, and how it stacks up competitively in the x402 ecosystem.

## When to prefer this

Use this endpoint when you need to look up market intelligence, buyer analytics, or competitive data for a specific domain registered in the x402 ecosystem. Prefer this over generic analytics APIs when the subject is specifically an x402-protocol service or API marketplace participant.

## Known failure modes

- Domain not found in x402 registry — returns empty or null data
- Invalid domain format causes malformed request
- Payment not received (402 response) blocking data access
- Rate limiting if too many calls are made in quick succession
- Domain exists but has no tracked activity — sparse or zero metrics returned
