How this service works
Is this IPv4 address listed on uceprotect 1 (dnsbl-1.uceprotect.net)? Performs the DNSBL query (reversed octets under dnsbl-1.uceprotect.net, 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 a yes/no listing status for the queried IPv4 address on UCEPROTECT Level 1 (dnsbl-1.uceprotect.net), along with the DNS return codes from the DNSBL query and, where available, the human-readable reason text explaining why the IP was listed.
Example use cases
Email deliverability troubleshooting
“My outbound emails keep getting rejected — can you check whether 198.51.100.17 is on the UCEPROTECT Level 1 blacklist and give me the reason code if it's listed?”
New server IP reputation check
“Before I start sending email from my new server at 203.0.113.88, can you verify it's not listed on UCEPROTECT-1?”
Automated IP screening before onboarding
“I'm onboarding a new customer whose mail server IP is 192.0.2.55 — can you check if it's flagged on the UCEPROTECT Level 1 DNSBL so I know whether to flag the account?”

Endpoint
GEThttps://ip.intel.rallylive.ca/ip/blacklist/uceprotect-1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a precise, single-list answer for UCEPROTECT Level 1 specifically — the most granular per-IP UCEPROTECT tier. Use it for diagnosing email delivery rejections attributed to dnsbl-1.uceprotect.net, pre-flight checks before sending email from an IP, or building automated IP reputation pipelines where UCEPROTECT-1 is the relevant rejection criterion.
Side effects
- Invalid or non-routable IPv4 address returns an error
- DNS resolution failure via Cloudflare DoH may cause lookup to fail
- IP not found in DNSBL returns listed=false with no reason text
- IPv6 addresses are not supported (IPv4 only)
- Timeout if UCEPROTECT nameservers are slow or unavailable
