A simple telegram bot written in Kotlin, for fetching price information about crypto currencies from CryptoCompare.
Originally this bot was requesting the public CoinMarketCap API. Because of their Professional API migration on December 4th, 2018 (Does not offer sufficient requests/endpoints in the free tier), I had to switch to another provider.
You can browse all currencies on CryptoCompare through Inline Queries.
Just call the bot by its username and a query in the text input field. For example: @PriceLeechBot eth.
Select a result and you'll get the most important information as a rendered image via Telegram.
You can try it out here.
| Command | Usage | Description |
|---|---|---|
| /coin | /coin eth | Request price details about a coin |
| /help | /help | Displays the help |
| /start | /start | Displays the welcome message |
In order to run the bot on your own machine, you have to set your telegram bot api token as an environment variable:
$ export CMBOT_TELEGRAM_TOKEN=YOUR_API_KEYDownload the latest jar release and run the following command:
$ java -jar cmbot-<version>.jar$ git clone https://github.com/yashino91/cmbot.git
$ cd cmbot/
$ mvn assembly:assembly$ docker build -t cmbot .
$ docker run -e "CMBOT_TELEGRAM_TOKEN=YOUR_API_KEY" cmbot$ java -jar target/cmbot-<version>.jarThe configuration is done in the config.yaml file, located in the resource directory.

| autoclearMessages | Deletes sent photo messages automatically if enabled |
