# is-email-hosted-by-one-com-bulk

> is-email-hosted-by-one-com-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 concurrently to determine whether each domain's email is hosted by One.com, returning ordered results 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-one-com-bulk-9be41c77
```

Example prompt: Can you check these 15 domains — example1.com, example2.com, example3.com, etc. — and tell me which ones have their email hosted by One.com? I need the results in the same order I gave them.

## When to prefer this

Choose this endpoint when you have a list of 2–20 domains and need to check One.com email hosting status in a single API call rather than making sequential single-domain requests. It is ideal for batch enrichment workflows, portfolio audits, and CRM lead enrichment where concurrent processing and ordered results matter. If you only have one domain, use the single-domain variant instead.

## Known failure modes

- Domain does not exist or has no MX records — per-item error field populated
- DNS lookup timeout for one or more domains — reflected in failure count
- Invalid or malformed domain names in the input list — per-item error
- Batch exceeds 20-domain limit — request rejected
- Rate limiting or upstream DNS resolver unavailability

## How this service works

Bulk is email hosted by one com: 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 (one per input domain) each containing a boolean indicating whether the domain's email is hosted by One.com, a per-item error field if the check failed for that domain, and a top-level failure count indicating how many items could not be resolved.
