## FAQ

### How does the news collection pipeline work?

Our automated pipeline continuously monitors 500,000+ news sources worldwide. We discover new articles through RSS feeds, sitemaps, and proprietary crawlers. Each article is fetched, cleaned, and processed through our NLP enrichment engine which extracts entities, analyzes sentiment, categorizes content, and detects duplicates. The entire process from publication to API availability takes less than a minute.

### What NLP processing is applied to each article?

Every article passes through multiple NLP stages: language detection (50+ languages), automatic categorization into topics (business, sports, technology, etc.), sentiment analysis (positive, negative, neutral with confidence scores), named entity recognition (people, organizations, locations, brands), readability scoring, keyword extraction, and AI-generated content detection.

### How quickly can I integrate the APITube News API?

Most developers integrate APITube within hours, not days. We provide official SDKs for Python, JavaScript, PHP, Java, Kotlin, Swift, Ruby, Go, and 20+ more languages. Our REST API follows standard conventions with comprehensive documentation, interactive examples, and a free tier for testing. Simply sign up, get your API key, and make your first request in minutes.

### How does APITube ensure data quality and accuracy?

We implement multiple quality control measures: source verification and ranking algorithms, duplicate detection to eliminate redundant content, captcha and paywall detection, spam filtering, content validation, and continuous monitoring of data accuracy. Our publisher ranking system helps you prioritize authoritative sources over low-quality content.

### What is the typical latency for accessing news data?

APITube delivers sub-100ms API response times for most queries. Breaking news typically appears in our system within less than a minute of publication. Our globally distributed infrastructure ensures fast access regardless of your location. We also support webhooks for real-time notifications when new articles matching your criteria are published.

### How does story clustering and duplicate detection work?

Our algorithms analyze article content, entities, and publication timing to group related articles into stories. When multiple publishers cover the same event, we cluster them together and identify the original source. This helps you track story evolution, measure coverage breadth, and avoid processing duplicate content across different publishers.

### Can I access historical news data through the API?

Yes, APITube provides access to years of historical news data. You can search archives using the same powerful filters available for current news: date ranges, topics, sources, locations, sentiment, entities, and more. Historical data is invaluable for trend analysis, research, training ML models, and building comprehensive news monitoring solutions.

### How do I filter and search for specific news content?

APITube offers 65+ filters for precise news discovery: search by keywords with boolean operators, filter by publication date, source, country, language, category, topic, sentiment, entity mentions, publisher rank, and more. You can combine multiple filters in a single query to retrieve exactly the news content you need for your application.
