Hi Pix4D Support Team,

I noticed that your [Pix4D Cloud Demo](https://cloud.pix4d.com/demo) application utilizes an API endpoint like `https://api.webgis.pix4d.com/bumblebee/v0/search?q=12&type=PROJECTED` to search for coordinate reference systems.

We would like to integrate a similar coordinate reference search feature into our internal tool and were wondering whether this API is publicly available for use, and if so, whether there is any official documentation, usage policy, or authentication process we should follow.

Looking forward to your guidance!
