## 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 domain-da-pa-checker-0d6e31a4 -d '<json body>'
```

Example prompt: Can you check the Domain Authority and Page Authority scores for example.com so I can gauge how strong it is for SEO?

## When to prefer this

Use this endpoint when you need quick DA/PA metrics for a single domain as part of an SEO audit, link prospecting workflow, or competitive analysis. Prefer this over full SEO suite APIs when you only need authority scores without crawl data or keyword rankings.

## Known failure modes

- Invalid or malformed domain input returns an error
- Domain not indexed or too new may return zero or null scores
- Network timeout if the upstream DA/PA data provider is slow
- Missing required domain parameter results in a 400 bad request
- Rate limiting or payment failure causes a 402 response
