API ImageSearch

I’m playing around with API ImageSearch

When I’m running the Image Search using bbox, can I somehow say that I only want to have images with camera_type = “equirectangular” or “spherical”?

Here is the pitch:
I plan to develop a little geo guesser app, but I only want to show actual 360 imagery (more enjoyable)…
I have a list of 500 famous locations in the world with their lat/lng pairs, and obviously, I would like to go to the nearest point where this kind of imagery is available…

Third menu button along the top left is filter and this has a 360 only option

Yes, but how can I do that via API?
