## 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 is-email-hosted-by-ionos-mail-bulk-57936488
```

Example prompt: Check all 15 domains in my list — example.com, acme.org, and the others — and tell me which ones have their email hosted by IONOS Mail; I need the results in the same order I gave them.

## When to prefer this

Prefer this endpoint over the single-domain variant when you have 2–20 domains to check and want to minimize round-trips and cost; it processes all domains concurrently and returns results in input order. Choose this when building pipelines that enrich CRM lists, research email infrastructure for a set of companies, or validate partners in bulk. For a single domain, the non-bulk sibling is sufficient. For monitoring changes over time, prefer the watch variant.

## Known failure modes

- Exceeds 20-domain limit — request rejected or truncated
- Individual domain DNS lookup failure — per-item error field populated, failure count incremented
- Invalid domain format in input — per-item error returned
- Network timeout to Cloudflare DoH — item marked as failed
- All items fail — high failure count returned with no positive results

## How this service works

Bulk is email hosted by ionos 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 per-domain results matching the input order, each indicating whether the domain's email is hosted by IONOS Mail (same answer as the single-domain endpoint), plus a per-item error field and an overall failure count for items that could not be resolved.
