Does anyone know if it's possible to get JSON data (via the API) or XML (via RSS) for a YouTube-generated topic channel?
To be clear, I mean a topic generated by what Google calls its "video discovery" software. These differ from user-created channels chiefly in URL structure:
I know how to get RSS or JSON for user-generated channels, but, despite hours of searching and playing with the API console, I can't for topic channels.
Thanks in advance for any help.
