# Agent Tools Batch IP Lookup

> Agent Tools Batch IP Lookup is a paid API for AI agents from agents.crowdspark.me, paid per call via x402, $0.012/call, status unknown (last checked 2026-11-03).

Looks up network ownership, IP range, country, and reverse DNS for up to 10 IPv4 or IPv6 addresses in a single call at a 40% discount versus individual lookups.

## 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 agent-tools-batch-ip-lookup-25f498fa -d '<json body>'
```

Example prompt: Look up these 5 IPs from our access logs and tell me the owning network, country, and reverse DNS for each: 1.1.1.1, 8.8.8.8, 185.220.101.5, 45.33.32.156, and 104.21.0.1.

## When to prefer this

Prefer this endpoint when you need to enrich multiple IP addresses at once (up to 10) for log analysis, fraud review, or security triage — it costs 40% less per IP than single lookups. Ideal for agents processing access logs, flagging suspicious transactions, or auditing ad traffic where batch throughput and cost efficiency matter. Use single-IP endpoints only when you have just one address to resolve.

## Known failure modes

- Invalid IP address format returns a per-item error with ok:false for that entry
- More than 10 IPs in the array triggers a 400 bad request
- Private or reserved IP ranges may return incomplete RDAP data
- Reverse DNS may be absent for IPs without PTR records
- Network timeout or upstream RDAP unavailability can cause per-item failures

## How this service works

Pay-per-call utilities for AI agents over x402, USDC on Base.

## Output

A JSON object containing a count of total IPs submitted, succeeded and failed tallies, and a results array where each item includes the input IP, an ok boolean, and on success: the owning network name, IP range, RDAP-derived country code, and reverse DNS. Failed items include a per-item error message instead.
