Verified status badge
Put this on your website or in a bid packet. It reads the state’s record live every time someone loads it, so it is never a screenshot of a good day. Free, and you don’t need to claim this listing to use it.

</a>The badge shows whatever the CSLB record says — including a suspension or lapsed coverage. There is no paid version and no way to change what it displays. That is what makes it worth showing. The same data as JSON if you’d rather build your own.
