Oftentimes, when searching products on Amazon, I want to see the products with the best ratings. More often than not, when sorting by Customer Ratings, Amazon will display products that have a 5-star rating from just 1 rating, which is not enough of a sample size to tell me much about those products.
So how can I search Amazon for 5-star-rated products that have received a minimum of X ratings (e.g. 10) and only then sort by ratings?
Can this only be done via their API or can this be done on their website directly via some kind of advanced search?
You can't do this with the API - Amazon removed star ratings (and review count) from it back in 2010, and the API now only shows them as part of a block of reviews in an iframe. So the only way to extract this information is to scrape Amazon - either the site itself, or inside those frames - which of course they do not take kindly to!

When scraping amazon reviews I always hit a wall at 5,000 reviews even when the product has 40,000. Is there any way to get past this barrier and scrape more?
To obtain more pages when scraping directly from search results, you can use filters to divide the search into smaller parts. For example reviews with star ratings may be searched first for one star, then two, etc. This of course does not promise all the results, but would increase your chances. Some filters may be more numerous but harder to implement, such as tags or usernames.
Alternately, access the data directly through their API and/or become an affiliate through their Amazon Associates program.
I'm building an integration for my warehouse and using Amazon's API's to get product information from UPC. I've ran into a number of times where a result comes back accurately from the GetMatchingProduct on MWS API but not from the Product Advertising API. Even Vice Versa has occurred.
Why might this be? Is there a reason I should just use one or the other?
Example: UPC - 363824072463
MWS brings back ASIN - B0057UUHGU which is the relevant one that also comes back when you just search Amazon. However the Product Advertising API does not return this in its list of results at all.
We have found that often times new, or recently changed items take a little while to correctly populate in the Product Advertising API.
Also, for what you say your purposes are, I would be cautious relying on the Product Advertising API. It is a sales tool, so sometimes when given an out-of-stock item, for instance, it will return results of a different item (maybe similar, maybe was variated with it, etc) as the purpose of that API is to drive sales to Amazon.
I'm a technical person with in-depth knowledge on Python and its framework. I've build an ecommerce store using Django-Oscar. I've multiple products in my store.
My store offers a large assortment of products in the Electronics category. A new and upcoming sub-category is surveillance and security systems. However, due to the varied nature of products in this category, the products are distributed across “Home Security” (Under Appliances) and “Security Systems”, etc. (under the Computers & Laptop > Office Equipment). A better understanding of the market segments is required for better positioning these products.
I reviewed Maplin, another e-store that provides same category of products on its store for better placing of my products.
Since I'm not a business analyst or a sales person, I want to get some recommendations/suggestions on how my e-commerce store can structure the products to increase conversion based on your review of the Maplin Storefront and my own product mix in this category. The constraint is that I cannot create a separate level 1 category for surveillance and security systems.
i tried Google on where should a particular product be placed to increase the conversion rate, but to little fortune. Also, I tried finding other SO portals where this type of question is a fit, but couldn't find any. So, if you can let me know the appropriate portal for this kind of question, it will be of great help!!! You can provide your recommendation/suggestions here as well.
Thanks!!! Appreciate your help!!!

So I'm working on an application that has a feature that generates a list of 100 or so artists that are similar to those in the user's music catalog using the Echo Nest API. Then, a user can supply a certain year, and, based on the similar artists, the application will return a list of albums that were released on that year.
The only problem is that I have no idea how to filter albums based on year. The Echo Nest API doesn't really do much with albums. The Discogs and Last.fm APIs work with albums, and the Discogs API has data about albums' release dates, but there is no way to filter an initial query by release date. For example, if I have the artist Fleet Foxes and I want to filter it by albums released in 2011, there is no option to search for albums by the Fleet Foxes confined to release dates of 2011.
The only option I can really see at this point is iterating over EVERY album an artist has and only adding those albums that meet my specifications. However, this is obviously very heavy on both the APIs and my server, especially considering that many of the artists in the list of 100 similar artists will have no albums that match my criteria and that many artists have well within the range of 100 albums when you take into consideration singles, remixes, etc.
Does anyone see a better way of doing this?
If an API really doesn't have any way to filter by year, then yes, of course you will have to pull down all of the releases and filter them after the fact.
If you think this is a burden on your code and/or their server, you should file a feature request to add the filtering.
However, you should make sure first that they really don't provide such a thing. Most REST APIs separate "fetch" and "search". For example, http://api.example.com/artists/12345/releases may not have any way to filter it, but http://api.example.com/search?type=releases&artist=12345&year=2011 may exist.
Without looking into all of the APIs in detail, a quick check of Discogs' "Run a search query" docs shows that you can include a year criterion in the search (although it looks like maybe you can't actually search by artist ID, just by artist name?).
Anyone know if it's possible, by using Amazon's API, to return all books on sale by one particular seller? For example, if I want to return all books by this seller:
http://www.amazon.co.uk/gp/aag/main?ie=UTF8&sshmPath=at-a-glance&isAmazonFulfilled=0&marketplaceID=A1F83G8C2ARO7P&isCBA=&orderID=&asin=B000002UUH&seller=A2UHPMPOX7FENB&isPopup=
You can see in the url the unique id. However, on Amazon's notes for ItemSearch:
MerchantId - An optional parameter you can use to filter search results and offer listings to only include items sold by Amazon
So I'm thinking 'only include items sold by Amazon' means you can only limit by amazon unless anyone knows a way of doing it?
It used to be be possible by doing a brute force search with the Seller* API calls. However these calls have been deprecated since Nov 1 2011, so you're out of luck. If you happen to be working for this particular seller (instead of being simply a customer or a competitor), you'll want to use the APIs available to the seller (MWS) to download inventory reports.
