Crypto News Aggregator

What does Crypto News Aggregator do?

Crypto News Aggregator collects and enriches articles from five of the most trusted cryptocurrency news sources — CoinDesk, Cointelegraph, Decrypt, CryptoSlate, and The Block — via their public RSS feeds in a single run. Each article is automatically scored for market sentiment, impact level, urgency tier, and narrative tags so you can filter for signal instead of noise. No API key is required.

Why use Crypto News Aggregator?

• Five top-tier sources in one call — CoinDesk (tier-1), Cointelegraph, Decrypt, CryptoSlate, and The Block are fetched in parallel so you always get the broadest crypto news coverage without managing multiple integrations.
• Built-in sentiment analysis — every article receives a sentiment_signal (very_bullish → very_bearish) and a numeric sentiment_score, making it easy to feed headlines directly into trading pipelines or LLM summarisers.
• Market impact scoring — the market_impact_score (0–100) flags articles about hacks, ETF decisions, regulatory actions, and major exchange events so high-stakes stories rise to the top automatically.
• Narrative tagging and coin detection — each article is tagged with active market narratives (ETF_flows, regulation, AI_tokens, defi, layer2, etc.) and the coins it mentions (BTC, ETH, SOL, and more), enabling precise downstream filtering.
• Pay-per-article pricing — at $0.001 per article, a 150-article run costs $0.15, making this one of the most affordable ways to automate crypto news collection at any scale.

FAQ

Do I need an API key to run this Actor? No. All five sources are fetched from their public RSS feeds using standard HTTP requests. No account registration or API key is required for any source.

How fresh is the news data? RSS feeds are updated by each publisher on their own schedule — typically every 15–60 minutes. The freshness_minutes and urgency_tier fields on each article tell you exactly how old each story was at the time of fetching. For near-real-time monitoring, schedule runs via Apify Schedules at 15–30 minute intervals.

Can I filter news to a specific coin or topic? Yes. Use the keyword input to filter by any term — coin name (Bitcoin), ticker (ETH), topic (regulation), or any other string. The filter matches against both the article title and the summary, and only matching articles are returned (and charged).
