In this post, I'll demonstrate a simple way to display data from API requests directly on desktop panels using Python and Conky.
Objective
The goal is to fetch information from an API and show it on a desktop panel. For this example, I'll use Python for the API requests and Conky to create the panels.
We’ll fetch the Bitcoin exchange rates in USD and BRL using the
Python Script: btc_data.py
Below is the Python script that retrieves Bitcoin rates and formats the output for the Conky panel:
CODE
import requests
API_URL = "https://economia.awesomeapi.com.br/json/last/BTC-USD,BTC-BRL"
try:
response = requests.get(API_URL)
data = response.json()
btc_usd = data.get("BTCUSD", {})
btc_brl = data.get("BTCBRL", {})
usd_alta = f"$${float(btc_usd.get('high', 'N/A')):,.2f}"
usd_baixa = f"$${float(btc_usd.get('low', 'N/A')):,.2f}"
brl_alta = f"R$${float(btc_brl.get('high', 'N/A')):,.2f}"
brl_baixa = f"R$${float(btc_brl.get('low', 'N/A')):,.2f}"
formatted_data = (
"\n\n${color white}BTC - USD\n${color}${color green} High: ${color}${color white}"+usd_alta+"\n${color red} Low: ${color}${color white}"+usd_baixa+"\n\n"
"${color white}BTC - BRL\n${color}${color green} High: ${color}${color white}"+brl_alta+"\n${color red} Low: ${color}${color white}"+brl_baixa+"\n"
)
print(formatted_data)
except Exception as e:
print(e)
Conky Configuration: btc_ck.conf
Here’s the configuration file for Conky. It runs the Python script every hour (3600 seconds) and displays the formatted output:
CODE
conky.config = {
default_color = '#afafaf',
own_window = true,
own_window_type = 'normal',
own_window_transparent = true,
own_window_colour = '#000000',
own_window_hints = 'undecorated, skip_taskbar',
use_spacer = 'right',
border_inner_margin = 20,
alignment = 'middle_right',
use_xft = true,
double_buffer = true,
font = 'Monospace:size=8:style=semibold',
gap_x = 80,
update_interval = 1.0,
}
conky.text = [[
${image /home/.../bitcoin-btc-logo.png -n -p 50,1 -s 25x25}
${execpi 3600 python3 /home/.../btc_data.py}
]]
Key Points:
- API Data: Fetching Bitcoin’s high and low prices in both USD and BRL.
- Update Frequency: The panel updates every hour via the execpi function.
- Styling: Some basic customization is applied to improve the panel’s appearance.
Running the Project
- Save the Python script (btc_data.py) and the Conky configuration file (btc_ck.conf) in the desired directory.
- Update the file paths in btc_ck.conf as needed (e.g., Python script location, Bitcoin logo image).
- Start Conky with the configuration:
CODE
conky -c /path/to/btc_ck.conf
