Filebeat OSS custom module cannot do API polling

I am trying to create some new modules for filebeat OSS but to create that I need API polling so that beats are able to fetch the data from a given url and parse it. To implement this I tried using httpjson input plugin but found that it is part of their licensing and not OSS version. is there any other way that I will be able to get data into filebeat with the help of API polling?
