How this service works
Is this IPv4 address listed on spamrats (spam.spamrats.com)? Performs the DNSBL query (reversed octets under spam.spamrats.com, 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 whether the queried IPv4 address is listed on the SpamRATS DNSBL (spam.spamrats.com), the DNSBL return code(s) associated with the listing, and the human-readable reason text if the list publishes one. Non-listed IPs return a clear negative result.
Example use cases
Email server deliverability check
“Before I send a bulk campaign, can you check whether my mail server IP 198.51.100.22 is blacklisted on SpamRATS? I want to know if it's listed and why.”
Suspicious inbound connection screening
“We're getting email from 203.0.113.99 that looks spammy — can you check if that IP is on the SpamRATS blacklist and give me the listing details?”
IP reputation audit for security team
“I need to know if 192.0.2.77 is currently flagged by SpamRATS — check the DNSBL and tell me the return code and any reason text they publish.”

Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/spamrats?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, single-list DNSBL check specifically against SpamRATS (spam.spamrats.com) rather than a multi-list aggregate check. Ideal when you want the SpamRATS return code and reason text for a specific IP, and need a lightweight per-IP lookup with a clear yes/no answer and low cost per call.
Side effects
- Invalid or non-routable IPv4 address returns an error or empty result
- DNS resolution failure via Cloudflare DoH may cause lookup timeout
- IPv6 addresses are not supported (IPv4 only)
- SpamRATS list temporarily unavailable causes lookup failure
- Rate limiting or payment issues may block repeated rapid queries
