Using Claude Code for Domain Names

If you're looking for a startup name, try this: use Claude Code to do it for you.

Instead of manually brainstorming domains for hours, I gave Claude Code three things:

a domain availability API
a naming strategy
permission to explore and test ideas

Then I just watched it cook.

Step 1: Give Claude an API to check domains

First I gave Claude the endpoint for checking domain availability.

GET api.vercel.com/v1/registrar/domains/{domain}/availability

You can generate a token from /account/settings/tokens in your Vercel dashboard.

Now Claude can programmatically test domains.

Important: don't smash the rate limit.

Step 2: Give it a naming strategy

Instead of saying "find a cool name", I gave Claude a strategy.

Example:

Find startup names using animals + action verbs that imply running or executing tasks.

Examples:

crowrun
lynxsnap
foxblitz
elkflash

This works surprisingly well for AI/agent style products.

Claude generated hundreds of combinations and checked them automatically.

I bought: lemonrun.com, waddlego.com and yoha.ai yesterday :)

Step 3: Let it run parallel searches

Claude then started exploring different directions in parallel:

animals + verbs
mythical creatures (dragons, ravens, etc.)
Game of Thrones style references
one-word .ai domains
foreign words that sound English
archaic dictionary words
niche glossary terms (maritime, blacksmithing, etc.)

It even rate-limited itself to avoid hitting 100 requests/minute.

Step 4: The interesting discovery

One-word .com domains are basically gone.

We tested ~400 candidates using multiple strategies and almost everything was taken.

.ai on the other hand is still a goldmine.

Good results came from:

foreign words
phonetic constructions
suffix hacks (like words ending in ai)
obscure vocabulary

Examples that were still available:

byre.ai
fosco.ai
yawl.ai

Grab them if you want :)

The takeaway

For good domains, you need to be searching a space other people aren't searching.

Claude is great at this because it can:

generate thousands of ideas
test them automatically
run multiple strategies in parallel

It's you going to godaddy.com and exploring different domain names, but at scale :)

The prompt I used (simplified)

Find startup domain names using animal + action verb combinations.

Check availability using:
GET /v1/registrar/domains/{domain}/availability

Generate ~100 candidates per batch.

Run multiple strategies in parallel.
Respect rate limits (100 requests/minute).
Focus on .com and .ai.

Then Claude just went off exploring.
