Best Practices and Tips​

API Key Management​

• Use personal API keys for higher rate limits and dedicated quotas
• Set EVENT_REGISTRY_API_KEY environment variable for security
• Monitor usage through EventRegistry dashboard to avoid limits

Query Optimization​

• Use specific category URIs for targeted results rather than broad searches
• Combine category and source filtering for precise content control
• Limit results appropriately for your processing capacity

Date Range Strategies​

• Use ISO format (YYYY-MM-DD) for all date parameters
• Omit dateTo for ongoing "breaking news" monitoring
• Use dateFrom only for "from this date forward" queries

Performance Considerations​

• Lower limits (50-100) for real-time applications
• Higher limits (200-500) for batch processing and analysis
• Consider pagination for very large result sets
