# IP Listed on SORBS DUL Bulk Check

> IP Listed on SORBS DUL Bulk Check 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 IPv4 addresses in one call against the SORBS DUL (Dial-Up List) DNSBL and returns 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 ip-listed-on-sorbs-dul-bulk-check-f5372502
```

Example prompt: Check these 15 IP addresses against the SORBS DUL dial-up blacklist all at once and tell me which ones are listed and if any checks failed: 192.0.2.1, 198.51.100.5, 203.0.113.22 [and 12 more].

## When to prefer this

Use this endpoint when you need to check multiple IPs (up to 20) against the SORBS DUL blacklist in a single API call rather than making individual requests. It is more cost-efficient and faster for batch workloads compared to calling the single-IP endpoint repeatedly. Prefer it when processing email sender lists, firewall log IPs, or any scenario where you hold a list of IPs to screen for dynamic/dial-up status simultaneously.

## Known failure modes

- Individual IP check fails (network or DNS timeout) — reported in per-item error field, failure count incremented
- Invalid IP address format in input — per-item error returned
- Batch exceeds 20 IPs — request rejected or truncated
- Service unavailability — entire batch call returns error

## How this service works

Bulk ip listed on sorbs dul: 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 per-IP results matching the input order, each indicating whether that IP is listed on SORBS DUL (the dial-up/dynamic user list), along with a per-item error field if the check failed for that IP, and an overall failure count for the batch.
