Check a single domain

The quickest way to ask "is this name free?" or "who owns this?" is the Quick Domain Check box at the top of the Radar page.

Run a check

1. Open app.norcube.com → DomainRadar.
2. Type the domain into the check box.
3. The button next to the input shows the current mode (Availability by default); the dropdown arrow switches between:
   • Availability Check — "Quick check if the domain is registered".
   • Verified — "DNS/RDAP/WHOIS-verified availability, 0% false positives".
   • Basic Info — "Registrar, registration, update, and expiry date".
   • Full WHOIS/RDAP — "Complete WHOIS/RDAP data including raw response".
4. Run the check.

When to pick which mode — and what each costs — is covered in Check modes.

Reading the result

• A green banner — "This domain is available!" — or a red one — "This domain is not available."
• Available domains get a Register on Namecheap link (what that does).
• Basic Info / Full results add a detail panel: availability, the method that answered, registrar, created / last-updated / expiry dates — and for Full, the raw RDAP response (pretty-printed JSON) and raw WHOIS response, each with a Copy button.
• Every result has a star — one click adds the domain to Saved Domains with this result attached.

Re-check a domain later

Saved domains carry their last result, which goes stale. On the Saved Domains page (and the saved-domains card on Radar), each row has a Recheck button that opens a mode-picker dialog — "Choose the check mode for this domain." — and runs a fresh check. The row updates with the new result.

Rate limits

Single checks are limited to 600 per hour per organization and 200 per hour per user; beyond that you'll get a 429 — see Limits and errors. Anything that would bump into those limits belongs in a bulk check anyway.

When to pick which mode

• Checking a candidate name for a launch — Availability or Verified; ownership data doesn't matter yet.
• Investigating a suspicious domain — Full: you want the raw record.
• Triaging a Brand Monitor detection — the hit already includes registration data from its automatic enrichment; go Full only if you need the raw responses.
• Checking a whole list — bulk check, always.
