Plumb Registry is answering right now. Last checked 3 min ago. It exposes 3 tools.
Search and verify fire protection contractor licenses (TX SFMO, CA CSLB C-16) from state records.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
