# Hostname to IPs Bulk Lookup

> Hostname to IPs Bulk Lookup is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Resolves up to 20 hostnames to their IP addresses with hosting attribution in a single concurrent batch call, returning results in input order with per-item error reporting.

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 hostname-to-ips-bulk-lookup-3f313f70
```

Example prompt: Look up the IP addresses and hosting providers for all 20 domains in my list — example.com, acme.org, testsite.io, and 17 more — all at once and tell me which ones failed.

## When to prefer this

Choose this endpoint when you have a list of 2–20 hostnames that all need IP and hosting attribution resolution, and you want to minimize latency and API call overhead compared to making individual /host/ips calls. It's ideal for batch enrichment pipelines, bulk domain audits, and any agent workflow that accumulates a list of domains before processing. For a single domain, prefer the non-bulk /host/ips endpoint instead.

## Known failure modes

- Individual domain resolution failures return a per-item error field rather than failing the whole batch
- Exceeding the 20-domain limit may result in a request error
- Invalid or malformed hostnames return per-item errors
- Domains with no DNS records return empty IP lists with error indication
- Network timeouts for individual items populate the error field for that item only

## How this service works

Bulk hostname to ips: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /host/ips endpoint (Hostname to IPs with hosting attribution). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input domain list, where each item contains the resolved IP addresses and hosting attribution data (same as the single /host/ips endpoint), plus a per-item error field for any resolution failures, and a top-level count of how many items failed.
