# IP Listed on Spamhaus SBL Bulk Check

> IP Listed on Spamhaus SBL 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 2026-10-12).

Checks up to 20 IP addresses in a single concurrent call to determine if each is listed on the Spamhaus SBL (Spam Block List), returning results in input order with per-item errors 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-spamhaus-sbl-bulk-check-10c3298e
```

Example prompt: Check these 15 IP addresses against the Spamhaus SBL blacklist in one batch and tell me which ones are listed and if any checks failed: 1.2.3.4, 5.6.7.8, 9.10.11.12 ... (list all 15).

## When to prefer this

Choose this endpoint when you have multiple IP addresses (up to 20) that all need Spamhaus SBL status checked simultaneously. It is more efficient and cost-effective than calling the single-IP endpoint repeatedly, as all IPs are processed concurrently and results are returned in input order. Prefer this over the single endpoint whenever your agent holds a list of IPs to screen.

## Known failure modes

- More than 20 IPs submitted — batch limit exceeded
- Invalid IP address format in list causes per-item error
- Spamhaus SBL lookup timeout results in per-item error with failure count incremented
- Empty input list returns no results
- Network/upstream Spamhaus API unavailability causes elevated failure counts

## How this service works

Bulk ip listed on spamhaus sbl: 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

Returns an ordered array of results matching the input IP list. Each item contains the Spamhaus SBL listing status (same fields as the single-IP endpoint), a per-item error field if the individual check failed, and an overall failure count across the batch.
