Running Jasmine tests at regular intervals

Hello,

I have several web apps using Meteor, and I am using Jasmine + Velocity (as defined on https://github.com/Sanjo/meteor-jasmine) to write tests for my apps.

These applications are using external APIs that sometimes change, and therefore breaking my applications. I wanted to know what would be the best way to automatically run these jasmine tests, every 24 hours for example, and get an alert when something breaks.

I thought about using a private GitHub repository + Travis CI Pro, but I wanted to know if there was a free or better alternative out there. Thanks!
