I have created a 13x13 led matrix with Serpentine ON is their any way i can change color of each pixel Individually from api using c# or python any examples i am trying to create an app to do custom painting over led matrix?
Sure can. There are a couple tools to do send images. Like Pixel Art Converter - WLED Project
And if you want to take the DIY approach, it is documented here JSON API - WLED Project

Thanks for the help! I have another question: Is it possible to set multiple custom images and execute a simple looped effect? For instance, turning LED numbers 1, 2, and 3 on and off sequentially every 2 seconds. How can I achieve this using the JSON API? Also, is there any way I can create a new preset using the JSON API?
The tool linked above is old , there is already a new tool integrated with wled ( just type http://wled-ip/pxmagic.htm )
In this new tool you can do gifs and the way it works is by saving mutiple presets and a playlist for you
