## 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`):

```

Example prompt: Can you check whether Barracuda Networks is authorized in the SPF records for these domains: acme.com, widget.io, techcorp.net, and 10 others I'll paste in — I want to know which ones are configured for Barracuda and which aren't, all in one go.

## When to prefer this

Use this endpoint when you need to check Barracuda SPF authorization for multiple domains (up to 20) in a single API call rather than making individual requests. It is ideal for batch enrichment workflows, compliance audits, or reporting pipelines where you hold a list of domains and want concurrent processing with ordered results and per-item error visibility.

## Known failure modes

- Domain does not exist or has no SPF record — per-item error field populated
- DNS lookup timeout for one or more domains — reflected in failure count
- Invalid domain format in input — item marked as error
- Batch exceeds 20 domain limit — request rejected
- Network or upstream DNS resolver failure — error in affected items

## How this service works

Bulk spf authorizes barracuda: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of per-domain results matching the input order, each indicating whether the domain's SPF record authorizes Barracuda mail servers, plus a per-item error field for any failures and an overall failure count for the batch.
