How this service works
Bulk dnsbl check: up to 20 ips in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /dns/blacklist endpoint (IP blacklist). Batch enrichment for agents that hold a list. $0.01 per batch.
Output
Returns an ordered array of DNSBL check results matching the input IP list, with each item containing the same fields as the single /dns/blacklist endpoint (blacklist status, listing details), plus a per-item error field for failed lookups and a top-level count of failures across the batch.
Example use cases
Email campaign pre-send IP audit
“I have these 18 sending IPs for our email marketing platform — can you run a bulk DNSBL check on all of them before we launch the campaign and tell me which ones are blacklisted?”
Suspicious traffic source vetting
“We've got a batch of 12 IP addresses from our access logs that look sketchy — can you check all of them against DNS blacklists in one go and flag any that show up?”
Hosting provider IP reputation sweep
“Here are 20 IP addresses from our new server block — run a bulk blacklist check on all of them and give me a count of how many are flagged along with the per-IP results.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/bulk/dns/blacklistWhen to prefer
Choose this endpoint when you have a list of 2–20 IP addresses to check against DNS blacklists and want to minimize latency and API calls via concurrent processing. It is more cost-efficient than calling the single /dns/blacklist endpoint repeatedly. Prefer it for batch enrichment workflows, pre-send email IP audits, or bulk threat intelligence pipelines where ordered, per-item results with error isolation are required.
Side effects
- Input list exceeds 20 IPs — batch size limit exceeded
- Invalid IP address format causes per-item error for that entry
- DNS resolution timeout for specific IPs returns per-item error
- Payment not completed — x402 payment required error
- All items fail — high failure count returned with per-item errors
- Malformed query parameter causes full request rejection
