How this service works
IDN / punycode converter and homograph check: converts between Unicode and ASCII (xn--) domain forms, lists the scripts used, flags mixed-script labels and confusable characters (Cyrillic а vs Latin a) that indicate homograph phishing risk. $0.01 per domain.
Output
Returns the punycode (xn--) ASCII form and the Unicode form of the domain, a list of Unicode scripts present in each label, a boolean or flag indicating mixed-script labels, and a list of any confusable/look-alike characters (e.g. Cyrillic 'а' vs Latin 'a') that signal homograph phishing risk.
Example use cases
Phishing domain investigation
“I got a suspicious email from 'suppоrt.apple.com' — can you check if that domain uses any Cyrillic or mixed-script characters that make it look like a legit Apple address but is actually a phishing site?”
IDN to punycode for DNS config
“I need to set up DNS records for the internationalized domain 'münchen.de' — can you convert it to its punycode xn-- form so I can use it in my zone file?”
Brand protection audit
“We own the brand 'paypal' and want to check if the domain 'раурal.com' is a Unicode lookalike using confusable characters — run a homograph check and tell me what scripts it uses.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dns/idnWhen to prefer
Use this endpoint when you need to detect homograph phishing domains, convert between Unicode and punycode domain representations, or audit internationalized domain names for mixed-script and confusable-character risks. Prefer this over generic DNS lookup tools when the security or authenticity of a domain's character set is in question.
Side effects
- Invalid or malformed domain name input returns an error
- Domains with unsupported or unregistered scripts may not resolve confusable mappings
- Network timeout if the upstream service is unavailable
- Payment failure via x402 protocol if insufficient USDC balance
