Accessing Planet Usable Data Masks

Is it possible to access the Planet Usable Data Masks through Sentinel Hub?

Hi Simon,
we are still exploring the usable data masks - as they are not available for a complete archive, we avoided them initially. They will come however, in mid-term future.

That being said, we are working at this point to add unusable data mask (UDM), which should become available very soon.

Some more info on this in this thread:

Ok thanks - I look forward to the update. Presumably even then, we will still need to order the data before we can see if the AOI is cloud free?

Correct. There is no way around that unfortunately, Planet does not support this.
