Aggregating Crypto News

Aggregating Crypto News

Overview

This skill aggregates cryptocurrency news from 50+ authoritative sources using RSS feeds. It provides real-time news scanning with filtering by coin, category, time window, and relevance scoring.

Key Capabilities:

• Multi-source aggregation from top crypto news sites
• Coin-specific filtering (BTC, ETH, SOL, etc.)
• Category filtering (DeFi, NFT, regulatory, exchange, etc.)
• Relevance scoring with market-moving keyword detection
• Multiple output formats (table, JSON, CSV)

Prerequisites

Before using this skill, ensure:

1. Python 3.8+ is installed
2. feedparser library is available: pip install feedparser
3. requests library is available: pip install requests
4. Internet connectivity for RSS feed access

Instructions

Step 1: Assess User Intent

Determine what the user is looking for:

• General news: No specific filters, use defaults
• Coin-specific: Extract coin symbol (BTC, ETH, etc.)
• Category-specific: Extract category (defi, nft, regulatory, etc.)
• Time-specific: Extract time window (1h, 4h, 24h, 7d)

Step 2: Execute News Aggregation

Run the news aggregator with appropriate filters:

# Default scan (top 20, past 24h, relevance sorted)
python {baseDir}/​scripts/​news_aggregator.py

# Coin-specific scan
python {baseDir}/​scripts/​news_aggregator.py --coin BTC --period 4h

# Category filter
python {baseDir}/​scripts/​news_aggregator.py --category defi --top 30

# Export to JSON
python {baseDir}/​scripts/​news_aggregator.py --format json --output news.json

# Multiple filters
python {baseDir}/​scripts/​news_aggregator.py --coin ETH --category defi --period 24h --top 15

Step 3: Present Results

Format and present the news to the user:

• Show source, title, age, and relevance score
• Highlight market-moving keywords if present
• Provide links for full articles
• Summarize meta information (sources checked, articles found)
