Hello,
Has anyone implemented this GitHub project https://github.com/sentinel-hub/field-delineation/blob/main/notebooks/01-data-download.ipynb without using batch API.
I do not know. Perhaps ask also on the GitHub repo?
Providing some more information on what kind of data access you had in mind would probably be a good idea as well.
That being said, it should be possible with some changes of code, but it is not on our priority.
