## 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

```

Example prompt: I have a list of domains — acme.com, globex.com, initech.com, and 10 others — can you check all of them at once to see which ones have their email hosted by Symantec MessageLabs?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to check Symantec MessageLabs email hosting status for all of them efficiently in a single call rather than making sequential individual requests. It is ideal for batch enrichment pipelines, sales intelligence workflows, or IT audits where concurrent processing and ordered results with granular error handling are important.

## Known failure modes

- DNS lookup failure for one or more domains — surfaced as per-item error, not a full batch failure
- Invalid domain format causing item-level error
- Exceeding the 20-domain batch limit may result in rejection or truncation
- Network timeout from Cloudflare DoH resolver reflected in per-item error field
- Non-existent domain returns error or false rather than a match

## How this service works

Bulk is email hosted by symantec messagelabs: 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, where each item contains a boolean indicating whether the domain's email is hosted by Symantec MessageLabs, a per-item error field for any lookup failures, and an overall failure count for the batch.
