出口 新闻及空气污染指数文章 到各种格式

Export news articles in JSON (default), XML, CSV, TSV, and XLSX formats. JSON is best for API integrations, XML for enterprise systems, CSV/TSV for data analysis and databases, and XLSX for business users working in Excel. Simply add the format parameter to any API request to change output format.

Both options are available. Export full article text for content analysis, archiving, or republication. Use description fields for summaries in news feeds or previews. Select specific fields to optimize payload size for your use case. Full content enables deep text analysis and NLP processing.

Article exports include image URLs, thumbnail references, and media metadata. Access featured images for display, extract all in-article images, or filter for articles with video content. Our exports provide image URLs rather than binary data for efficient bandwidth usage.

Yes, integrate our API with scheduling tools like cron, Airflow, or cloud schedulers. Query with date filters to export new articles since your last run. Build automated pipelines that export, transform, and load news data into your systems on any schedule.

Use date range filters to export historical news from our extensive archive. Export by day, week, or month for manageable file sizes. Our archive spans years of news data, enabling trend analysis, backtesting, and historical research across all supported formats.

Comprehensive metadata accompanies each article: publication timestamp, source details (name, URL, country, OPR rank), author information, categories, topics, extracted entities, sentiment scores, language code, word count, reading time, and breaking news indicators. Metadata enables filtering, analysis, and organization.

Make separate API requests with different format parameters to generate multiple export formats from the same query. Use scripting to automate multi-format exports if you need JSON for applications and CSV for analysis from the same dataset.

Exports support thousands of articles per request with pagination for larger datasets. Use filters to create focused exports that meet your needs efficiently. For very large historical exports, paginate through results or contact us for bulk data solutions with optimized delivery.
