Usage Examples

Example 1 — Simple domain check

Is recetaapp.com available?

check_domain({ "domain": "recetaapp.com" })

recetaapp.com is already registered and not available. Would you like me to check alternatives like recetaapp.net or recetaapp.io?

Example 2 — Multi-TLD check by name

Check if vendepan is available across common extensions.

check_domain({ "domain": "vendepan" })

Results for "vendepan":

✅ vendepan.com — Available → Register on Namecheap
✅ vendepan.net — Available → Register on Namecheap
✅ vendepan.io — Available → Register on Namecheap

Example 3 — Domain check for a pet care brand

I'm launching an online store for organic pet food. Suggest names and check which domains are free.

check_domain({ "domain": "petbowl" })

check_domain({ "domain": "pawfood" })

check_domain({ "domain": "organipet" })

I checked 3 names for your organic pet food store:

❌ petbowl.com — Already registered
✅ pawfood.com — Available → Register on Namecheap
✅ organipet.com — Available → Register on Namecheap

My recommendation: pawfood.com — short, memorable, and immediately communicates what the brand is about.

Example 4 — Startup naming workflow

Help me name my SaaS for remote team task management. Check which names are actually available.

check_domain({ "domain": "taskflow" })

check_domain({ "domain": "remotask" })

check_domain({ "domain": "syncteam" })

check_domain({ "domain": "flownest" })

Results for your SaaS naming:

❌ taskflow.com — Taken
❌ remotask.com — Taken
❌ syncteam.com — Taken
✅ flownest.com — Available → Register on Namecheap

flownest.com is available and works well — "flow" suggests productivity and "nest" suggests a home base for your team.
