## 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-c7dc7414 -d '<json body>'
```

Example prompt: Can you check the Moz domain authority, page authority, and spam score for these domains: ahrefs.com, semrush.com, and moz.com? Return up to 3 results.

## When to prefer this

Choose this endpoint when you need fast, structured Moz SEO metrics (domain authority, page authority, spam score) for domains known or suspected to be in the Moz Top 500 list, especially for link-building vetting, SEO benchmarking, or spam filtering workflows. It is pay-per-call with no charge on failed or empty runs, making it cost-efficient for conditional lookups. Prefer alternatives if you need metrics for arbitrary long-tail domains not in the Top 500 snapshot, or if you need real-time Moz API data beyond this curated snapshot.

## Known failure modes

- Domain not in Moz Top 500 snapshot — returns record with null fields
- Empty domains array with maxItems=0 — returns empty items list
- Invalid domain format — may return null match
- Rate limiting or payment failure — call not charged if run fails or is empty
- Requesting more than 500 items — capped at 500 by schema maximum

## How this service works

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

## Output

Returns a JSON object with a count, product label ('moz'), and an array of items each containing: the input domain, matched mozDomain, spam score, top-500 rank, page authority, domain authority, and linking root domains. Only domains present in Moz's Top 500 snapshot return records; unmatched domains return null fields.
