## 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 kiteendpoints-ai-domain-da-pa-checker-f2f5da40 -d '<json body>'

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

## When to prefer this

Use this endpoint when you need quick, pay-per-use DA/PA lookups without committing to a full Moz or Ahrefs subscription. Ideal for one-off domain checks, bulk vetting of backlink prospects, or pre-purchase domain evaluation where you only need authority scores rather than full SEO audit data.

## Known failure modes

- Invalid or malformed domain input returns an error
- Unknown or very new domains may return zero or null scores
- Rate limiting or payment failure results in 402 response
- Domain not found in the authority database returns empty result
- Network timeout if the underlying data provider is slow
