I've created a nodejs module that allows you to fetch information about anyone on repl.it and create posts and comments on repl.it talk. This is the source code, you can learn how to use it by reading the README.md file on the source code or by reading the readme on the npm package. This took me a while to made and I had to learn how to use something called graphql. If you find any bugs make sure to report them on the discord server or on this post. The repl is an example of using the API.
Shout out to @mat1 's python api.
that looks very similar to leondoescode's version https://repl.it/talk/learn/repl-talkjs-in-NodeJS/23176
