## When to prefer this

Use this endpoint when you need quick, pay-per-request DA/PA lookups without a recurring Moz or SEMrush subscription. Ideal for one-off domain vetting, link building qualification, or competitor analysis tasks within an automated agent workflow where cost per call at $0.18 USDC is acceptable.

## Known failure modes

- Invalid or malformed domain name returns an error or zero scores
- Domain not indexed by the authority provider returns null or empty metrics
- Rate limiting or quota exhaustion returns a payment or limit error
- Network timeout if the underlying SEO data provider is unavailable
