How this service works

Generate common typo and look-alike variations of a domain and check which are already registered — catches character swaps, omissions, additions, homoglyphs, and alternate TLDs so agents can detect typosquatting and brand-impersonation domains targeting a company.

Output

Returns a risk grade and score for the domain, a list of registered lookalike domains (with details per finding), a list of still-available variations, counts of registered vs available domains, and the total number of variations checked.

Example use cases

Example prompt

“Can you scan stripe.com for typosquat lookalike domains — check up to 50 variations and tell me which ones are already registered so I can see if anyone is impersonating us?”

Technical details

Endpoint

GEThttps://netintel-production-440c.up.railway.app/typosquat/scan?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to proactively audit a domain for typosquatting risk, detect potential phishing infrastructure, or monitor brand impersonation. Ideal for security teams, brand protection workflows, and domain portfolio audits where you need to enumerate and check registered lookalikes systematically rather than checking a single specific domain.

Side effects

Missing domain query parameter returns validation error
Domain without TLD is rejected
limit exceeding 50 is clamped or rejected
WHOIS/registration lookup timeouts for some variations may reduce coverage
Non-existent TLD may yield no results
