In my earlier article<\/strong><\/em><\/a>, I had briefly described the REST server I wanted to build for Krishnamurti Padhdhati<\/strong> <\/em>system of astrology. After a long time I have managed to complete the implementation and it is now ready for deployment.<\/p>\n

In this article, I will go over some of its features with the hope it will be useful to developers interested in building astrology applications, in particular, using the KP<\/strong><\/em> System.<\/p>\n

KPRest: A REST Engine<\/h3>\n

The product is named \u201cKPRest\u201d<\/strong><\/em> and as the name suggests, it is a REST server engine. The core engine is written in C++<\/strong><\/em> and is based on my astrology software called \u201cKPAstro\u201d<\/strong><\/em><\/a>. KPAstro<\/strong><\/em> is hugely popular among KP<\/strong><\/em> system followers and has users in many countries across the world. The inspiration for developing the REST engine was the many requests I received from application developers who wanted to build interesting astrology applications using the KP System, but who did not have the basic resource or the time to build the core astrology engine. KPRest<\/strong><\/em> solves this problem elegantly.<\/p>\n

Let us get back to the product. This is a Windows-based<\/strong><\/em> product and when you launch it, this is the startup screen:<\/p>\n

\"KPRest<\/a>
KPRest Application Window<\/strong><\/em><\/figcaption><\/figure>\n

To start the server, click \u201cStart\u201d<\/strong><\/em>. If you want to test the product in your browser, click \u201cOpen Browser\u201d<\/strong><\/em>. This will launch the default browser, which connects to the server and displays the initial message from the engine.<\/p>\n

\"Welcome<\/a>
Welcome Message in Browser<\/strong><\/figcaption><\/figure>\n

Let us say that we want to create a Natal<\/strong><\/em> chart. The request is made using the query \u201c\/natal\u201d<\/strong><\/em> with the following additional parameters (the values are just for example):<\/p>\n

Day = 13, Month = 6, Year = 1965<\/strong><\/p>\n

Hour = 10, Min = 30, Sec = 20<\/strong><\/p>\n

Latitude = 28:36:0 North<\/strong><\/p>\n

Longitude = 77:12:0 East<\/strong><\/p>\n

Standard Time, Time zone = GMT +5.5 hrs, Daylight Savings = 0<\/strong><\/p>\n

This could be entered as part of the URL<\/strong><\/em> as under:<\/p>\n

\"Creating<\/a>
Creating Natal Chart in Browser<\/strong><\/figcaption><\/figure>\n

 <\/p>\n

The system responds with an \u201cOK\u201d<\/strong><\/em>message.<\/p>\n

Once the chart is created, we can send other requests to the server, for example, to get the Planets\u2019<\/strong><\/em> positional details, Significators<\/strong><\/em>, Aspects<\/strong><\/em>, Bala<\/strong><\/em>, etc. Each request has a unique URL<\/strong><\/em> end point.<\/p>\n

Instead of interacting with the server via the Browser<\/strong><\/em>, it is more convenient to write a client application. Following this idea, I have implemented a Python<\/strong><\/em> program to interact with the REST<\/strong><\/em> server.<\/p>\n

Here is a sample output from the Python<\/strong><\/em> program. It creates a Natal<\/strong><\/em> chart (as we did in the Browser<\/strong><\/em>), prints the chart details for verification and fetches the Day Lord<\/strong><\/em>, Thithi<\/strong><\/em>, Hora<\/strong><\/em>, Karana<\/strong><\/em>, and Nithya Yoga<\/strong><\/em>:<\/p>\n

\"Creating<\/a>
Creating Chart in Python Client<\/strong><\/em><\/figcaption><\/figure>\n

Here is the code fragment for creating Natal<\/strong><\/em> and Horary<\/strong><\/em> charts:<\/p>\n

\"Creating<\/a>

The detailed information regarding various planets such as Position<\/strong><\/em>, Sign<\/strong><\/em>, House<\/strong><\/em>, Star<\/strong><\/em>, and the lords<\/strong><\/em> (Sign\/Star, Sub, Subsub, S3, and S4<\/strong><\/em>) can be retrieved.<\/p>\n

\"Planetary<\/a>
Planetary Details<\/strong><\/figcaption><\/figure>\n

Western Aspects<\/strong><\/em> between planets can also be obtained from the server. Here is a sample:<\/p>\n

\"Western<\/a>

Although it is not directly used in KP<\/strong><\/em> System, many astrologers make use of \u201cBala\u201d<\/strong><\/em> in their analysis. KPRest<\/strong><\/em> engine can calculate this too. Here is the Python<\/strong><\/em> code to get it from the server:<\/p>\n

\"Python<\/a>
Python Code for Retrieving Bala<\/strong><\/figcaption><\/figure>\n

Here is the output from the program:<\/p>\n

\"Bala<\/a>

There is a lot more that we can ask the engine to provide. As I mentioned earlier, the engine supports Natal<\/strong><\/em> as well as Horary<\/strong><\/em> (1 to 2193) charts. \u00a0<\/span><\/p>\n
