Making the api call

search_tags.rb

To request the a list of tags, we can use the get_trending_tags method:

api = Radiator::Api.new

api.get_trending_tags(nil, 100) do |tags|
  puts tags
end

Notice, the above example can request up to 100 tags as an array.

Example api call

If we want to get 10 tags starting from the tag named “music” …

api.get_trending_tags("music", 10) do |content| ...

Example api call using script

And to do the same with our tutorial script, which has its own default limit of 10. Internally, the api method only allows at most 100 results, so this tutorial will paginate the results to go beyond 100:

ruby search_tags.rb

Example Output

From the example we get the following output from our script:
