Automate Crypto News Analysis with n8n & GPT-4o

What This Automation Does

This workflow gets crypto news from many RSS feeds when you send a coin name to a Telegram bot.

It picks only news about your coin by using an AI keyword extractor.

Then it asks an AI model to make a short summary and market mood report.

The summary is sent back through Telegram as a message.

This helps a user save time and get clear info quickly.

Important Code and Prompt Snippets

Code to Filter Articles by Keyword

This Code node checks if the article mentions the extracted keyword in the title, snippet, or content. It uses lowercase to avoid case mismatches.

const term = $node["Set Query"].json.query.toLowerCase();
return items.filter(item => {
  const j            = item.json;
  const title        = (j.title || "").toLowerCase();
  const snippet      = (j.contentSnippet || j.description || "").toLowerCase();
  const fullContent  = (j.content || "").toLowerCase();
  return title.includes(term)
      || snippet.includes(term)
      || fullContent.includes(term);
});

Prompt for AI Summarization and Market Sentiment Analysis

This prompt instructs the AI to summarize news and describe the market mood for the keyword, listing article titles and links.

const q   = $node["Set Query"].json.query;
const list = items
  .map(i => `- ${i.json.title} (${i.json.link})`)
  .join("\n");
const prompt = `
You are a crypto-industry news analyst.
Summarize current news and market sentiment for **${q}** based on these articles:
${list}

Answer in 3 parts:
1. Summary of News
2. Market Sentiment
3. Links to reference news articles
`;
return [{ json: { prompt } }];

Customization Ideas

• Add extra RSS Feed Read nodes with other crypto news sources to get broader news coverage.


• Change the OpenAI model in the summarization node to try newer AI versions or a different style.


• Modify the prompt text to request shorter summaries, more or less detail, or different tone.


• Edit the Telegram message format to include emojis, timestamps, or price alerts.


• Adjust the keyword extraction node’s prompt to fine-tune how it picks filtering keywords.


• Make sure the Telegram send node uses dynamic chat IDs from sessionId for multi-user support.

Common Issues and Fixes

Telegram messages don't send. Check that chatId is set dynamically using the stored sessionId field. Also, disable privacy mode in @BotFather.

No news after filtering. The keyword might not match articles. Check the keyword extractor output and make filter code case-insensitive.

OpenAI API errors. Validate your API Key and check usage limits on your OpenAI dashboard.
