Use when you need to find WHO covers a topic on YouTube and do not have a handle yet: building a creator shortlist, mapping who owns a niche, or sizing a competitive field before you commit. Returns channels, not videos, so it does not reward whoever titled one video well. Billing is one unit per search TERM and the rows are free, so ask for a large maxItems on few terms rather than the reverse. Use youtube.channel when you already know the handle, youtube.similar_channels when you have one channel and want others like it, and youtube.videos when you want videos rather than the channels behind them.
Price
$0.0030 per event. That is the rate you pay for each event the call returns, so the total depends on how many it produces. Billing follows actual usage, so a call that returns fewer events costs less, and a call that costs nothing to serve is free.discover and inspect also return a ceiling for your specific request, which is a maximum you will never be charged above.
Input
Goro forwards your input to the underlying tool unchanged, so any field the
tool accepts works here even if it is not listed above.
