How this service works
Bulk ip listed on spamrats noptr: 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
An ordered array of per-IP results matching the input list order, each containing whether the IP is listed on the SpamRATS NOPTR DNSBL, a per-item error field indicating any lookup failure, and a top-level failure count summarizing how many items could not be resolved.
Example use cases
Email sender IP reputation screening
“Before we process these inbound emails, check these 15 sender IPs against the SpamRATS NOPTR blacklist all at once: 198.51.100.1, 203.0.113.5, 192.0.2.10, 10.10.10.10, 172.16.0.1, 185.220.101.5, 91.108.4.1, 77.88.8.8, 8.8.8.8, 1.1.1.1, 104.21.0.1, 162.159.0.1, 45.33.32.156, 23.239.9.133, 46.101.0.1. Tell me which ones are blacklisted.”
Bulk threat intel enrichment for SOC
“Our SOC collected 20 IPs from suspicious login attempts overnight. Can you run them all through the SpamRATS NOPTR DNSBL check in one go and report which ones are flagged and if any lookups failed?”
Pre-send mail relay validation
“We're about to start a marketing campaign through these 8 relay IPs. Check them all against the SpamRATS NOPTR blacklist right now so we can swap out any listed ones before we start sending: 203.0.113.10, 203.0.113.11, 203.0.113.12, 203.0.113.13, 198.51.100.20, 198.51.100.21, 192.0.2.50, 192.0.2.51.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/blacklist/spamrats-noptr?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you have a list of 2–20 IPv4 addresses to check against SpamRATS NOPTR and want to minimize API calls and latency by processing them concurrently in one batch. Use the single-IP endpoint if you have only one address to check. Choose this over generic IP reputation services when you specifically need SpamRATS NOPTR (no-PTR-record spam source) classification.
Side effects
- DNS resolution timeout for one or more IPs — item-level error field is populated, failure count incremented
- Invalid IP address format in input — per-item error returned
- Batch exceeds 20 IPs — request may be rejected or truncated
- Network connectivity issue to DNSBL server — failure reflected in per-item error
- Payment of 0.10 USDC not completed — 402 Payment Required response returned before any lookups
