Every 30 minutes, three Telegram channels update with breaking news — curated from 22 trusted RSS feeds, formatted in a clean breaking-news style, and posted with article images. The entire pipeline costs $0 per day to run.
No GPT API calls. No cloud functions. No monthly SaaS fees. Just Python, RSS, and cron.
Here's how I built it.
The Architecture
RSS Feeds (22 sources) → Python Script → Telegram Bot API → 3 Channels
↑
System Cron (*/30 * * * *)
That's it. No database. No queue. No Lambda. A single Python script runs every 30 minutes via cron, pulls fresh stories from RSS feeds, deduplicates against a JSON file, and posts to Telegram.
The Three Channels
🌍 The Daily Brief — World News
Sources: BBC World, BBC Top Stories, Al Jazeera, NPR World, The Guardian, PBS NewsHour
These are tier-1 news organizations with free RSS feeds. BBC provides media:thumbnail in their RSS, so we get images for free.
🤖 AI Pulse Daily — Tech & AI News
Sources: TechCrunch, Ars Technica, The Verge, Wired, VentureBeat, MIT Tech Review, Google AI Blog, Hacker News (100+ points), The Register, Engadget
Ten sources gives us roughly 97 stories per cycle. We post the top 3 new ones every 30 minutes.
₿ EZ Market Alpha — Crypto Markets
Sources: CoinDesk, CoinTelegraph, Decrypt, The Block, Bitcoin Magazine, CryptoSlate
Plus a separate bot that provides live prices, whale alerts, and AI-powered sentiment analysis.
The Code (Simplified)
The core is ~200 lines of Python. Here's the key logic:
def fetch_rss(url):
"""Parse RSS/Atom feed, extract title, URL, description, and image"""
resp = urllib.request.urlopen(url, timeout=10)
root = ET.fromstring(resp.read())
stories = []
for item in root.findall('.//item'):
image = None
# Try media:thumbnail (BBC), media:content, enclosure
thumb = item.find('{http://search.yahoo.com/mrss/}thumbnail')
if thumb is not None:
image = thumb.get('url')
stories.append({
'title': item.findtext('title'),
'url': item.findtext('link'),
'image': image
})
return stories
def extract_og_image(url):
"""Fallback: grab og:image from the article page (~0.1s)"""
html = urllib.request.urlopen(url).read(50000).decode()
match = re.search(r'og:image.*?content="(https?://[^"]+)"', html)
return match.group(1) if match else None
Image Strategy
-
RSS
media:thumbnail— BBC, Ars Technica, Wired provide images directly in the feed -
og:imagefallback — For feeds without images, we fetch the first 50KB of the article and extract the Open Graph image tag. Takes ~0.1 seconds. -
Telegram
sendPhoto— If we have an image, post as photo with caption. Falls back to text-only if the image fails.
Deduplication
def story_hash(title):
clean = re.sub(r'[^a-z0-9 ]', '', title.lower())
return hashlib.md5(clean[:80].encode()).hexdigest()[:12]
We hash the first 80 chars of each title and store them in a JSON file. Entries older than 7 days are pruned automatically.
Rate Limiting
- Max 3 posts per channel per run (9 total across all channels)
- 2-second delay between posts
- Runs every 30 minutes
- That's ~6 stories/hour per channel during active news hours
Why RSS Instead of AI Summarization?
I originally built this with LLM summarization — feed articles through Ollama, generate summaries, post them. It worked, but:
- Headlines are already summaries. Reuters, BBC, AP — their titles ARE the news. Adding AI summarization was redundant.
- Token cost adds up. Even with local models, processing 200+ articles every 30 minutes burns compute.
- Latency. RSS → format → post takes <5 seconds. Adding LLM summarization adds 30-60 seconds.
- Reliability. Fewer moving parts = fewer failures.
The Disclose.tv model works: short prefix ("JUST IN", "BREAKING", "NEW"), headline, one-line context, link. Clean, scannable, fast.
The Disclose.tv-Style Format
🌍 JUST IN - US economy unexpectedly sheds 92,000 jobs in February
The Labor Department reported a surprise decline in employment.

@TheDailyBriefNews
This format is optimized for mobile Telegram:
- Bold prefix catches the eye while scrolling
- Headline delivers the news in one line
- One sentence of context (from RSS description)
- Link for people who want the full story
- Channel handle for sharing
Self-Hosting This
The whole thing runs on a single Linux box. Requirements:
- Python 3 (standard library only — no pip packages)
- Telegram Bot API token (free from @botfather)
- Cron (literally every Linux system has this)
Total infrastructure cost: $0/month if you already have a server.
Results So Far
- 117 stories posted in the first day
- 22 RSS sources pulling reliably
- Zero failed posts (Telegram Bot API is rock solid)
- Images on ~80% of posts
What's Next
- Premium tier — Once we hit 1K+ subscribers, gate advanced features (custom alerts, topic filtering, AI analysis)
- Cross-platform — Same content pipeline to Discord, Slack, or email newsletter
- Engagement analytics — Track which stories get the most views/forwards
