# Is DNS Hosted By AWS Route 53 Bulk

> Is DNS Hosted By AWS Route 53 Bulk is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-18).

Bulk-checks up to 20 domains concurrently to determine whether each is hosted on AWS Route 53, returning ordered results with per-item errors and a failure count.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-dns-hosted-by-aws-route-53-bulk-f23d3137
```

Example prompt: I have a list of 15 domains — example.com, test.org, mysite.net, and 12 others — can you check which ones are DNS-hosted on AWS Route 53 all at once?

## When to prefer this

Use this endpoint when you need to check Route 53 hosting status for multiple domains (2–20) in a single call rather than making repeated single-domain requests. It is ideal for bulk enrichment workflows, domain portfolio audits, and pipeline stages where you already have a list. For a single domain, prefer the single-domain sibling endpoint to avoid batch overhead.

## Known failure modes

- Invalid or malformed domain names return per-item errors without failing the whole batch
- More than 20 domains submitted causes rejection or partial processing
- Domains with no DNS records may return indeterminate results
- Transient DNS resolution failures populate the per-item error field and increment failure count
- Network timeouts for individual domains increment failure count but do not abort the batch

## How this service works

Bulk is dns hosted by aws route 53: 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 the domain name, a boolean or status indicating whether it is hosted on AWS Route 53, a per-item error field (null on success), plus a top-level failure count summarizing how many items encountered errors.
