Using Cryptora

Using Cryptora is easy. In any Telegram chat, simply type @CryptoraBot and then any of the commands below. The requested information will pop up as a list on your screen, and you can tap on a result to share it with your chat. You can also create a new private chat with Cryptora if you'd like to interact with it separately.

Supported Commands

In a Telegram chat, type @CryptoraBot and then any of these commands to use Cryptora:

[cryptocurrency] – Type the name of any cryptocurrency, and Cryptora will retrieve essential information (price, market cap, circulating supply, and 24 hour percent change) and display it in a list. You can also type the cryptocurrency's shorthand abbreviation. For example, you can type bitcoin or BTC to get essential information about Bitcoin. The bot is not case sensitive, so you can type in any valid cryptocurrency name or its symbol in lower case or upper case. You can also type multiple cryptocurrencies, separated by commas, and send a list of cryptocurrency prices, percent changes, or market capitalizations in a single message. Cryptora automatically filters out duplicate and invalid entries. So, typing ripple, iota, xmr, nano, bitcoin will get you a list of their prices, market capitalizations, and percent changes that you can share with a chat.
news - Retrieve the latest 10 articles from CoinDesk.com and display them in a list. You can choose to share the article with your chat, or you can browse the latest cryptocurrency headlines.
global - Retrieve global statistics from CoinMarketCap, including the total market capitalization, the total 24 hour volume, bitcoin's dominance, and the number of active cryptocurrencies and markets.
gdax - Retrieve the trading price of Bitcoin, Bitcoin Cash, Litecoin, and Ethereum from the GDAX trading exchange.
[cryptocurrency] [date] - Type this command, replacing [cryptocurrency] with your desired cryptocurrency, and [date] with a date formatted in MM/DD/YYYY format (or Month Day, Year format), and Cryptora will retrieve the high, low, opening, and closing price - as well as the market capitalization - of the cryptocurrency on that date, if data is available. Relative dates work as well, so typing ethereum two weeks ago or ethereum yesterday will get you information about ethereum two weeks ago and yesterday, respectively.
top [x] - Type this command (replace [x] with any number less than or equal to 50) to see the top x cryptocurrencies, ranked by their market capitalization.
[x] [cryptocurrency] - Type this command (replace [x] with any number, and [cryptocurrency] with your desired cryptocurrency) to instantly convert an amount of cryptocurrency to U.S. dollars.
$[x] [cryptocurrency] - Type this command (replace [x] with any number, and [cryptocurrency] with your desired cryptocurrency) to instantly convert an amount of U.S. dollars to the desired cryptocurrency.
help - You can type help in Cryptora to get a list of the supported commands there.

How it was built

Cryptora was built using the python-telegram-bot framework. Data is retrieved from CoinMarketCap, using a combination of API access and webscraping. News articles are retrieved from CoinDesk through its RSS feed. The bot is hosted on RedHat OpenShift.
