Ask HN: Is there an API to get what is trending at this time?

I only know topsy.com, never used their api but they're twitter's only valid partner on trends and stats etc. http://about.topsy.com/support/api/ i hope it helps.

thanks!

Trendspottr. They were the first major player in this space I could remember. Their API can be found here https://trendspottr.com/api/

Yeah, I second TrendSpottr. They not only have an API for surfacing trends for any topic or keyword but also an API for trending alerts. http://trendspottr.com/api. I also use their trends dashboard Signal http://trendspottr.com/signal.

Perhaps http://buzzsumo.com might do what you're after? Their plan that includes the API is expensive if you just want to play around with it.
