Hi,
we are have our own custom tracking tool and looking to integrate Native Traffic Sources.
It seems that none of the Native Ad Networks have an API yet. How can we get all the ad insights like spend, click, impressions for our ads at least every hour or real time?
Our first solution would be to use our crawler, but there must be easier ways. 
Cheers and thanks
revcontent, yahoo gemini and outbrain have apis
taboola has a private api
you need to specifically request API access from them
None of the data, except Outbrain spend, is real-time in API. They do tend to give you "updated" stats every hour but it is still about 2 hours behind.
