## 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 tencent-exmail-bulk-email-host-checker-12ab1aa4
```

Example prompt: I have a list of 15 domains — alibaba.com, tencent.com, baidu.com, and 12 others — can you check which ones are using Tencent Exmail for their email hosting all in one go?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to check Tencent Exmail hosting for all of them efficiently in a single API call rather than making repeated single-domain requests. Ideal for batch enrichment pipelines, sales prospecting, or CRM workflows where throughput matters and you want ordered results with error handling built in.

## Known failure modes

- Domain DNS lookup fails — per-item error field is populated and failure count incremented
- Invalid or malformed domain input — item marked as error in results
- More than 20 domains submitted — request rejected or truncated
- DNS resolution timeout — per-item error returned
- Payment not fulfilled — request blocked with 402 response

## How this service works

Bulk is email hosted by tencent exmail: 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 corresponding to each input domain, where each item indicates whether the domain's email is hosted by Tencent Exmail (true/false), an optional per-item error field if the lookup failed, and an overall failure count for the batch.
