# is-email-hosted-by-hushmail-bulk

> is-email-hosted-by-hushmail-bulk is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-22).

Checks up to 20 domains at once to determine whether each domain's email is hosted by Hushmail, returning results in input order with per-item error fields and a failure count.

## 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-hushmail-bulk-b97aa26b
```

Example prompt: Can you check this list of domains — acme.com, privatecorp.io, and 18 others — and tell me which ones have their email hosted by Hushmail?

## When to prefer this

Use this endpoint when you have a list of 2–20 domains and need to determine Hushmail email hosting status efficiently in a single call. It is preferable over calling the single-domain endpoint repeatedly when batch throughput and concurrency matter. Choose this over general email provider detection tools when the specific question is Hushmail hosting.

## Known failure modes

- DNS lookup failure for one or more domains results in per-item error field populated and incremented failure count
- Invalid or malformed domain names cause per-item errors
- Exceeding 20 domains per call may result in rejection or partial processing
- Rate limiting or upstream DoH (Cloudflare) unavailability may cause transient failures

## How this service works

Bulk is email hosted by hushmail: 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 whether that domain's email is hosted by Hushmail (boolean), plus a per-item error field if the lookup failed. A top-level failure count summarizes how many items could not be resolved.
