## 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 moz-top-500-domain-authority-lookup-557ff77d -d '<json body>'
```

Example prompt: Can you pull Moz domain authority, page authority, and spam scores for these domains: techcrunch.com, wired.com, and theverge.com — up to 3 results from the Top 500 list?

## When to prefer this

Choose this endpoint when you need authoritative Moz SEO metrics (domain authority, page authority, spam score, linking root domains) specifically for domains likely to appear in the Moz Top 500. It is pay-per-call with no charge for empty results, making it cost-efficient for spot checks. Prefer alternatives if you need full-web domain coverage beyond the Top 500, real-time crawl data, or granular page-level metrics.

## Known failure modes

- Domains not in Moz Top 500 return no records (no charge)
- Empty domains array with maxItems of 0 returns no results
- Invalid domain format may result in no match
- Network or upstream Moz data unavailability returns error
- Exceeding maxItems cap of 500 is rejected

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.
