Inspiration for this project

As I'm always looking for different investments and higher capital returns, I decided to build a Twitter bot capable of creating new tweets ifself everyday with crypto info.

BTC, ETH e SOL were chosen in the first place. Upcomming versions might have different options.

  git clone https://github.com/DanielDomingueti/twitter-bot-bitcoin.git

  https://twitter.com/i/flow/signup

Get your account KEY to create requests following the link below

  https://developer.twitter.com/en/docs/twitter-api/getting-started/getting-access-to-the-twitter-api

Create the file twitter4j.properties (src/main/resources) and insert the keys as following

  oauth.consumerKey=API KEY from Twitter
  oauth.consumerSecret=API KEY SECRET
  oauth.accessToken=ACCESS TOKEN
  oauth.accessTokenSecret=ACCESS TOKEN SECRET

Run the Spring application and the cron will be execute at a given moment.
You can also make a request in this URL if you're willing to create a tweet instantly.

  POST http://localhost:8080/messari/post/

But if you just want to fetch data, here you go

  GET http://localhost:8080/messari/get/{cryptoSymbol e.g. BTC}

How does it work?

Brief explanation about the project's functionalities

Its core is based on a CRON method. Everyday at 10 a.m. and 22 p.m. the system make a request at /messari/get/{cryptoSymbol} and grab BTC, ETH and SOL's current price.
The service InsertTweetService process it and call the function execute() in PostTweet class to post a tweet.
You can easily change the cron's time in PostTweet
If needed, you can insert a tweet at the current moment at /messari/post
