Can The Amazon Product Api Be Accessed From Javascript (chrome Extension)

I've been playing about with Chrome extensions and one of the things I'd like to do is request product information from the Amazon Product Advertising API. The code to do this is

Solution 1:

Looking into this it really seems like this can't be done directly from Javascript without potentially exposing your secret key. The only options I've discovered are:

1. Host a server to do the work for you and talk directly to your server using Javascript
2. Use a hosted service that will do the signing for you. One example I've found is http://apisigning.com/service.html - basically for a fee they appear to sign the request for you. Note that I haven't tested this.

Sadly, I think both of these options are a bit more than I'd planned on using so I've given up on my extension for now. It's a bit disappointing that Amazon don't allow easier access to their data but I guess they feel they have to protect it from competitors.

Solution 2:

I guess you need a server to do your request! Lets the extension send the resquest to your server and there the request to amazon is done (php). The result of that you can use in your extension!
