Why this directory is different

License-first

Every listing starts from the state's own registration records, with registration numbers and expiration dates.

Re-verified regularly

Expired and lapsed registrations drop off on each refresh. Each page shows the date it was last verified.

Built for AI assistants too

Clean JSON, markdown and structured data on every page, so assistants quote accurate facts. See llms.txt.
