Recap
Working with 3rd party data sources is not that difficult as long as we know how to query them. Understanding their structure might be challenging especially when no much documentation provided.
For quick prototyping, use UI libraries / examples that provide ready to be used components out of the box as much as possible.
For open source projects, github actions is the service that has it all.
