Aggregating Crypto News
Overview
Aggregate cryptocurrency news from 50+ authoritative sources via RSS feeds with real-time scanning, coin/category filtering, and relevance scoring.
Prerequisites
- Python 3.8+ installed
- Dependencies:
pip install feedparser requests
- Internet connectivity for RSS feed access
Instructions
Assess user intent - determine filters needed:
- General news: no filters, use defaults
- Coin-specific: extract symbol (BTC, ETH, etc.)
- Category-specific: extract category (defi, nft, regulatory, etc.)
- Time-specific: extract window (1h, 4h, 24h, 7d)
Run the aggregator with appropriate filters:
# Default scan (top 20, past 24h, relevance sorted)
python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py
# Coin-specific scan
python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin BTC --period 4h
# Category filter
python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --category defi --top 30
# Multiple filters
python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin ETH --category defi --period 24h --top 15
Export results for downstream processing:
python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --format json --output news.json
Present results 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)
Output
Table showing articles ranked by relevance score (0-100) based on market-moving keyword detection, source authority, and recency:
