# Barracuda Blacklist Bulk IP Lookup

> Barracuda Blacklist Bulk IP Lookup is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-13).

Checks up to 20 IP addresses at once against the Barracuda blacklist/reputation database, returning concurrent results in input order with per-item error handling.

## 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 barracuda-blacklist-bulk-ip-lookup-14c061ae
```

Example prompt: Check all 15 IPs from my mail server list against the Barracuda blacklist in one batch and tell me which ones are flagged and if there were any errors.

## When to prefer this

Use this endpoint when you have a list of 2–20 IP addresses that all need Barracuda blacklist checks, as it processes them concurrently in a single API call at $0.10 flat — far more efficient than calling the single-IP endpoint repeatedly. Prefer it in batch enrichment pipelines, pre-send email deliverability checks, or security triage workflows where multiple IPs must be evaluated together.

## Known failure modes

- Input list exceeds 20 IPs — batch size limit exceeded
- Invalid IP format in list causes per-item error with that item's error field set
- Barracuda DNS lookup timeout for a specific IP increments failure count
- Payment not provided or insufficient — x402 payment required error
- Empty input list returns empty results array

## How this service works

Bulk ip listed on barracuda: up to 20 ips 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 IP list, each containing the Barracuda blacklist status for that IP (same detail as the single-IP endpoint), a per-item error field indicating any individual lookup failure, and a top-level failure count summarizing how many items could not be resolved.
