The Nintendo 3DS eShop was added in the June 2011 update for JP/EUR/USA.
From here, you can download Virtual Console games, 3D Classics, DSiware software, view screenshots, and 3D trailers for upcoming 3DS titles.
While eShop is loading, eShop will use command NIMS:CheckSysupdateAvailableSOAP. If a system update is available where title installation for system titles still needs finalized (or when the updated titles were not downloaded at all), eShop will then display the "system update is available" message.
The eShop application uses command AMNet:FinishInstallToMedia to finalize the SD title install (if the whole title is downloaded while eShop is still running), however, before using that command the eShop application also uses AMNet:FinishInstallToMedia to finalize installing all system titles (from system updates).
eShop QR Codes
eShop QR Codes can be scanned with the camera, allowing one to quickly navigate to the desired eShop title with just two clicks. The QR Codes themselves is a simple text/url QR, started with "ESHOP://" string followed by a decimal eShop content link id(same IDs used internally by eShop for all content) and then some special data, delimited by a dot symbol, which can be ommited.
In order for the QR-code string data to be valid for eShop, it must begin with "ESHOP://5", with the first ID being all decimal.

- New QR Code for Japanese "Photos with Super Mario" has a different code string: ESHOP://50010000013120.J00108Z00001.CD588EAE95A3A68D15C647DA2AC0945FD88F70AB8A31149E51C4B05FB927B0B8
- There is a link in the Japanese eShop [http://www.nintendo.co.jp/3ds/eshop/qrCode.html?####] where you can replace the #### with the Japanese eShop title's serial and you will get it's QR code. (i.e. http://www.nintendo.co.jp/3ds/eshop/qrCode.html?jcaj will get you the pushmo QR code)
- You could use Google's Chart API to create a QR code from the codes above: https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=ESHOP (replace the ESHOP text with the ESHOP:// link from one of the above)
NS eShop application parameters
This section describes the 0x1C-byte structure stored at the application parameters from APT:StartApplication, under the 0x300-byte buffer listed there.
|0x0||0x4||Unknown, usually 0x3?|
|0x4||0x4||Unknown, usually 0x0?|
|0x8||0x8||u64 binary eShop content ID, same ID from the first string in eShop QR-codes except in binary form.|
|0x10||0x10||This is the last string from the QR-code(if any), no NUL-termination.|
The ExtData File System for eShop is as follows:
root ├── icon ├── boss │ └── TIGER100.tmp └── user
|File||Details||Size||Firmware Introduced||Plain text|
|icon||Duplicate from application ExeFS. Always image 00000002||0x36C0 Bytes||2.0.0-2||Download_EUR|
|TIGER100.tmp||Always image 00000003.||0xCE47 bytes (varies?)||2.0.0-2|
The eShop pulls its music from a static, region-specific link in a format similar to the following:
https:// a248.e.akamai.net/f/248/103046/10m/npdl.c.app.nintendowifi.net/p01/nsa/CtfKXACbUPl8s7lk/BGM1/US_BGM1 , where region is one of the primary system regions (JP, US, EU, KR, etc.) Support also exists for 'BGM2', but this seems to be unused. The music is held in a BOSS container.
The format consists of a brief XML header describing the audio (including the date it was set as the main eShop theme, loop times, size, etc) followed by a raw AAC stream. Tools such as FFmpeg can handle rebuilding this stream with ADTS headers for proper time info and such.
The Home Menu uses nearly the same format for the Theme Shop's background music.
eShop uses the following domains over HTTPS:
These domains are used by NIM:
ninja.ctr.shop.nintendo.net and samurai.ctr.shop.nintendo.net contain the bulk of the eShop information.
Common Parameters to ninja and samurai
For every request to the ninja and samurai servers, three parameters are always sent, though are not necessarily required:
|shop_id||depends on the URL, usually no||Describes which eShop instance should be used. 1 indicates the 3DS eShop, 2 indicates the Wii U eShop. 3 seems to yield the same results as 2. Values greater than 3 or less than 1 are invalid. Defaults to 2 or 3 if not given.||unsigned integer||1|
|lang||no||Describes the language. Seems to be an ISO 639-1 code in lower case. Every eShop region has a default language that is used if this parameter is not given. Some regions have multiple languages, such as CA (en and fr).||string (two characters)||depends on region and eShop settings; for US: en|
|_type||no||Describes whether the client wants to receive JSON or XML. This parameter seems actually unused and the servers always return XML.||string||json|
samurai.ctr.shop.nintendo.net (samurai) provides metadata about titles. The samurai server provides the backend for the eShop title search.
Common parameters described above can always be sent.
|/samurai/ws/region/titles||Fetches the title list, containing the content id (not the 3DS title id), the product code and the localized title name||All of these are optional.
|/samurai/ws/region/news||eShop news section||(none)|
|/samurai/ws/region/telops||Scrolling news on the top screen||shop_id is required|
|/samurai/ws/region/directory/(long long unsigned int) and /samurai/ws/region/directory/~(string)||(unknown)||(unknown)|
|/samurai/ws/region/title/content id||Returns information about the title, more verbose than /titles.||(none)|
|/samurai/ws/region/contents||Seems identical to /titles.||see /titles|
|/samurai/ws/region/genres||Returns a list of human-readable genre names and their corresponding genre id.||(none)|
|/samurai/ws/region/publishers||Returns a list of human-readable publisher names and their corresponding publisher id.||(none)|
|/samurai/ws/region/title/content id/aocs||Returns a list of add-on contents/downloadable content and prices in eShop region currency.||(none)|
ninja.ctr.shop.nintendo.net (ninja) contains the seeds for the new 9.6 crypto, pricing information and handles actions that require authentication, such as purchases. Authentication information seems to be obtained from the act:u sysmodule and works through OAuth2.
|/ninja/ws/region/title/content id/ec_info||Contains information about the title. Such as title id, content size, and if available, the 9.6 crypto seed||(none)|
|/ninja/ws/titles/id_pair||Provides the content id for the given title id, or vice versa.||title_id or ns_uid is required.|
|/ninja/ws/region/tax_locations||Provides the tax location ID||postal_code is required.|
|/ninja/ws/service_hosts||Provides CCIF and Samurai servers||country and shop_id is required.|
|/ninja/ws/country/region||Various eshop related information for a given region||(none)|
|/ninja/ws/country/region/replenish_amounts||Provides the amounts of money you can replenish to your account.||(none)|
Server changes following the November 2, 2015, maintenance
Pre-v10.0 eShop used an URL like this: "%s/samurai/ws/%s/title/%llu/other_purchased?shop_id=1&lang=%s&_type=json". That URL was removed with v10.0. That URL was requested when trying to load eShop app-pages. Following the maintenance mentioned above, this page was removed from the server, which broke pre-v10.0 eShop app whenever it tried to access that page.
