## 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 bulk-strato-mail-mx-hosting-checker-33746399
```

Example prompt: I have a list of 15 domains — acmecorp.de, berlinstartup.com, and 13 others — can you check all of them at once to see which ones have their email hosted by Strato Mail?

## When to prefer this

Choose this endpoint when you have multiple domains (up to 20) to check for Strato Mail hosting simultaneously and want to minimize round trips and cost. It processes all domains concurrently and returns results in input order, making it far more efficient than calling the single-domain endpoint repeatedly. Ideal for list enrichment workflows, CRM data augmentation, or batch sales intelligence pipelines specifically targeting Strato Mail users.

## Known failure modes

- Domain not found or invalid — per-item error field populated, boolean result absent
- DNS lookup timeout via Cloudflare DoH — per-item error recorded, contributes to failure count
- Exceeding 20-domain batch limit — request may be rejected or truncated
- Network error reaching the endpoint — full batch failure with HTTP error status
- Malformed input list — validation error returned before processing begins

## How this service works

Bulk is email hosted by strato mail: 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 results matching the input domain list. Each item contains a boolean indicating whether email is hosted by Strato Mail, the domain queried, any per-item error message if the lookup failed, and a summary failure count across the batch.
