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
