Should I do API requests server side or client side?

I am trying to make a web app using ExpressJS and Coffeescript that pulls data from Amazon, LastFM, and Bing's web API's.
Users can request data such as the prices for a specific album from a specific band, upcoming concert times and locations for a band, etc... stuff like that.

My question is: should I make these API calls client-side using jQuery and getJSON or should they be server-side? I've done client-side requests; how would I even make an API call from the server side?
I just want to know what the best practice is, and also if someone could point me in the right direction for making server-side API requests, that would be very helpful.

Thanks!

There's are two key considerations for this question:

  1. Do calls incur any data access? Are the results just going to be written to the screen?
  2. How & where do you plan to handle errors? How do you handle throttling?

Item #2 is really important here because web services go down all of the time for a whole host of reasons. Your calls to Bing, Amazon & Last FM will fail probably 1% or 0.1% of the time (based on my experiences here).

To make requests users server-side JS you probably want to take a look at the Request package on NPM.

It's often good to abstract away your storage and dependent services to isolate changes and offer a consolidated and consistent web api for your application. But sometimes, if you have a good hypermedia web api (RESTful responses link to other resources), you could reference a resource link from another service in the response from your service (ex: SO request could reference gravatar image/resource of user). There's no one size fits all - it depends on whether you want to encapsulate the dependency or integrate with it.

It might be beneficial to make the web-api requests from your service exposed via expressjs as your own web-apis.

Making http web-api requests is easy from node. Here's another SO post covering that:

well, the way you describe it I think you may want to fetch data from amazon, lastfm and so on, process it with node, save it in your database and provide your own api.

you can use node's http.request() to fetch the data and build your own rest api with express.js
