NseData is a Ruby gem designed to interact with the National Stock Exchange (NSE) of India's API, providing an easy-to-use interface for developers to retrieve stock market data. The gem offers a high-level API for most users and a lower-level API for advanced users who need more control over the interactions.
Features
- Fetch stock market data from multiple NSE APIs
- High-level and low-level API interfaces
- Simple and clear error handling for HTTP requests
- Ruby 3.1 and 3.2 support with a test matrix across different OS
- Easy integration with CI/CD and coverage tools
Installation
Add this line to your application's Gemfile:
gem 'nse_data'
And then execute:
bundle install
Or install it yourself as:
gem install nse_data

Usage
High-Level Interface
The high-level interface is designed to be simple and user-friendly. You can instantiate an object and call the available methods:
require 'nse_data'
puts NseData.list_all_endpoints # Returns all the available APIs in the library
puts NseData.fetch_all_indices # Returns the response.body of allIndices endpoint of NSE
Low-Level API
For advanced users, the lower-level APIManager class offers more control over requests:
require 'nse_data'
api_manager = NseData::APIManager.new
response = api_manager.fetch_data('index_names')
puts response.body # Returns index names in JSON format
where index_names
is the name of the API routing to the path of https://www.nseindia.com/api/index-names
Configuration
The gem uses an api_endpoints.yml
file located in the config directory. This file maps API names to their respective endpoint URLs.
Example
all_indices:
path: "allIndices"
description: "Fetches data of all available indices."

- all_indices: Fetches data of all available indices.
- circulars: Provides a list of circulars.
