Zapier - Create Instant Triggers

I'm using Zapier's CLI developer kit to create some app. But when I create a "new object" trigger, the url supplied in official document looks just like a "get all" trigger:

method: 'GET',
url: 'http://example.com/api/objects'

Seems Zapier won't know when a new object is created instantly, instead, Zapier checking all the objects every 5 mins.

Their plans shows even the most expensive plan can just provide checking every 5 mins.

So how can I create instant triggers? That said, I want to send a request to Zapier every time an object is created in my app.
