Naming Signal is answering right now. Last checked 1 min ago. 32 installs a week from npm.
Evidence-first naming: briefs, sprints, exact domain checks, finalist research. Read-only.
Today is the operative word: we check Naming Signal every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 1 min ago.

This one needs environment variables set before it will start:
NAMING_SIGNAL_API_KEY (NamingSignal user API key created at https://namingsignal.com/developers. Required for hosted tool calls.), NAMING_SIGNAL_API_URL (API origin. Defaults to https://namingsignal.com; set http://localhost:3000 for a local development server.).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, but you need an API key from its owner to call it.
