Name checker
Check a product, startup or project name in one go: whether the domains are registered, and whether the GitHub and npm names are free.
Checks .com, .dev, .ai, .io, .app and .co, plus GitHub and npm. Free, 20 checks a day without a key.
How it works
Domain status comes straight from the registries (RDAP, with WHOIS where a registry has no RDAP), so "registered" means a registration exists today. "Not registered" means the registry has no record; a few names are still reserved or sold at premium prices. GitHub and npm are checked against their public registries.
For agents and scripts
curl -s https://searchwire.dev/v1/names/check \
-H "content-type: application/json" \
-d '{"name": "yourname", "tlds": ["com", "dev", "ai"]}'
With a Searchwire key the same call also returns the name's monthly search volume. See the API docs.
