TIL, NASA has an API:
Welcome to the NASA API portal. The objective of this site is to make NASA data, including imagery, eminently accessible to application developers. This catalog focuses on broadly useful and user friendly APIs and does not hold every NASA API.
Requires obtaining an API key, which I assume is pretty straightforward. Wonder if its image search is good for querying Webb and Hubble telescope imagery.
