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.
Example use cases
Pre-send email deliverability screening
“Before we send this email campaign, check all 18 sending IPs against the Spamhaus SBL in one go and flag any that are blacklisted so we can swap them out.”
Security ops IP triage
“I've got a list of 12 suspicious source IPs from our firewall logs — can you batch-check all of them against Spamhaus SBL right now and give me a summary of which ones are blocked?”
Onboarding customer IP vetting
“We're onboarding a new client and they've given us 8 mail server IPs — check them all against the Spamhaus SBL at once and let me know if any are flagged before we whitelist them.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/blacklist/spamhaus-sbl?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
