## 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 forgemesh-seo-authority-compare-1a5d8650 -d '<json body>'
```

Example prompt: Compare the open-web domain authority for these five sites: hubspot.com, semrush.com, moz.com, ahrefs.com, and searchengineland.com — rank them from strongest to weakest.

## When to prefer this

Choose this endpoint when you need to compare relative open-web domain authority across a set of 2–20 domains simultaneously using reproducible, Common Crawl-derived graph metrics rather than proprietary third-party DA scores. Prefer it over single-domain authority lookups when competitive ranking or side-by-side benchmarking is the goal. It is particularly well-suited for competitive SEO audits, link-building prospect evaluation, and domain acquisition decisions where you need a deterministic, unbiased authority signal across multiple candidates in a single call.

## Known failure modes

- Fewer than 2 domains submitted — validation error
- More than 20 domains submitted — exceeds maxItems limit
- Invalid domain format (e.g. URL with path instead of bare domain) — may return null or error for that entry
- Very new or obscure domains with no Common Crawl presence may return zero or null authority scores
- Payment failure or insufficient USDC balance — 402 response blocking the call

## How this service works
