🤖 Telegram Bots

Cloudflare Analytics Bot

A custom Python bot that connects to the Cloudflare GraphQL API and generates live charts using matplotlib (dark theme), sent as images directly in Telegram. Controlled entirely via a persistent reply keyboard — no commands needed.

Keyboard buttons:

Button	Chart type	Data source
📊 Trafic	Line chart + area fill	HTTP requests / 24h
📡 DNS	Line chart	DNS queries / 24h
🍕 Status	Pie chart	HTTP status code distribution
🌍 Țări	Horizontal bar chart	Top 10 countries by requests
🔗 Pagini	Bar chart	Top 10 most visited paths
🏠 Hosts	Bar chart	Top hosts (subdomains)
🛡️ Threats	Line chart	Blocked attacks / 24h
📋 Sumar	Text + multi-photo	All metrics combined
🖥️ Server	Text	Live CPU, RAM, disk, IP, uptime

All charts are generated on-the-fly, saved as PNG and pushed via Telegram sendPhoto. Dark background (plt.style.use('dark_background')), 120 DPI, with grid and value annotations on bars.

Screenshot Bot (micu_shot_bot)

A utility bot for remote server interaction via Telegram.

🤔 Why?

Because it's fun to see how different languages approach the same web problem. Each service started as a learning experiment and ended up staying in production. The COBOL app is probably the most cursed thing I've ever deployed.
