How this service works
Is this IPv4 address listed on spamhaus xbl (xbl.spamhaus.org)? Performs the DNSBL query (reversed octets under xbl.spamhaus.org, via Cloudflare DoH) and returns listed yes/no with the return codes and, where the list publishes one, the reason text. One list, one precise answer. $0.01 per lookup.
Output
Returns a yes/no listed status indicating whether the IPv4 address appears on xbl.spamhaus.org, along with any DNSBL return codes and, where available, the human-readable reason text explaining why the IP is listed (e.g. CBL/Abuseat listing, Spamhaus policy block).
Example use cases
Pre-send email deliverability check
“Before we send out our marketing campaign, can you check whether our mail server IP 203.0.113.22 is listed on Spamhaus XBL so we know if we'll hit spam filters?”
Incident response IP triage
“We're seeing suspicious outbound traffic from 198.51.100.77 — can you check if it's already flagged on Spamhaus XBL and what the reason text says?”
New user IP reputation screening
“A new account just signed up from IP 45.33.32.156 — is that address on the Spamhaus XBL exploits blocklist?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/spamhaus-xbl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, single-list check specifically against Spamhaus XBL (the Exploits Block List, covering IPs used by malware and botnets). Prefer it over generic IP reputation APIs when you need the authoritative XBL result code and reason text, or when you are building email delivery pipelines, spam filters, or security workflows that specifically reference XBL listing status. For broader multi-list checking, consider sibling endpoints on the same platform.
Side effects
- Invalid or non-routable IPv4 address provided — returns error or no-result
- IPv6 address supplied — endpoint only supports IPv4
- DNS resolution failure via Cloudflare DoH — may return transient error
- Rate limiting or payment failure — returns 402 or related error
- IP is valid but not listed — returns listed: false with no reason text
