How it works ?

Description

This API is a C++ Microsoft Windows library that interfaces with the Global Datafeeds Server Systems. The API talks to nimbleDataProPlus Desk (nimbleDataProDesk.exe) and does not provide direct connections to our servers for the components developed using the API. Instead, nimbleDataProPlus Desk (our Connection Manager) manages the session with our servers while the API provides a developer-friendly interface to query and retrieve the data.

To use the API, it requires Connection Manager (nimbleDataProDesk.exe) alongwith other necessary files as installed by nimbleDataProPlus Installer. nimbleDataProPlus Desk is a stand alone application that receives data from GFDL Servers, decompresses it, stores it and distributes it to each client application connected to it.

So if you are a company having commercial software and implement this API, all your users need to do is to subscribe to nimbleDataProPlus / nimbleDataPlusLite - either directly from our website or through you - to access realtime / EOD data of the supported exchanges into your software application.

Once the API is implemented by you, your users can subscribe to our data products  directly from us (nimbleDataPlusLite ORnimbleDataProPlus) OR you can decide to resell our data products and earn additional reseller's commission from us.

Programming Languages
C, C++, MFC

Pricing
Fees are dependent on which category Developer falls under, as described below.

A. If you are Developer having commercial software application with retail users and wishing to incorporate GFDL data into your software :

• There is no charge for API usage i.e. Global datafeeds API is available free to download and use, subject to terms and conditions as laid out in the Agreement. 
• The Developer must have an active annual subscription of our datafeed (nimbleDataProPlus).

B. Others :

• There will be annual fees of INR 30000+Taxes (600USD) to download and use Global Datafeeds API. The fees are to be paid in advance before access to API is granted and is subject to other terms and conditions as laid out in the Agreement. The fees will be non-refundable under any circumstances.
• In addition to API Usage fees mentioned above, the Developer must have an active annual subscription of our datafeed (nimbleDataProPlus).

If you are a startup developing a software application for retail users but haven't gone live yet OR if you do not have a sizeable userbase yet OR if you are not supporting any other realtime datafeed at the moment, you fall under B category - at least for 1st year. You will stand a bright chance of migration to Category A and waiver of API usage charges from 2nd year onwards, subject to the developments and performance in 1st year.
