How this service works
Bulk ip listed on cbl: 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 per-item results matching the input IP list, each containing the CBL listing status (listed or not), a per-item error field if the lookup failed, and an overall failure count for the batch.
Example use cases
Pre-send email deliverability check
“Before we send this email campaign, check all 18 of our outbound mail server IPs against the CBL blacklist and flag any that are listed so we can pull them before sending.”
Security triage for suspicious traffic
“I've got a list of 12 IPs that showed up in our firewall logs — can you run them all through the CBL blacklist and tell me which ones are flagged as spam sources?”
Onboarding IP reputation screening
“We're onboarding a new customer and they gave us these 20 IPs they'll be sending from — batch-check them all against the CBL and give me a breakdown of which are clean and which are blacklisted.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/blacklist/cbl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check multiple IPv4 addresses against the CBL DNSBL in a single call. It is more efficient and cost-effective than calling the single-IP endpoint repeatedly for lists of 2–20 addresses. Ideal for pre-send email deliverability pipelines, batch security triage, or onboarding workflows where a set of IPs must be screened at once.
Side effects
- Input list exceeds 20 IPs — batch size limit exceeded
- Invalid IPv4 address format in input list — per-item error returned
- DNSBL query timeout for one or more IPs — per-item error with failure count incremented
- Empty input list — request rejected
- Network error reaching CBL DNSBL — partial results with failure count
