Categories are available on all plans including free. Tags are assigned automatically by Newsdata.io&#8217;s AI\/ML pipeline and cover a wide range of named entities, events, and topics. You can include up to\u00a0<strong>5 tags per query<\/strong>\u00a0using the\u00a0<code>tag<\/code>\u00a0parameter. The full list of categories and available tags is documented at\u00a0<a href=\"https:\/\/newsdata.io\/documentation\">newsdata.io\/documentation<\/a>.[\/vc_column_text][vc_column_text]\n<h3>Can I combine the category and tag parameter in the same request?<\/h3>\n<p>Yes, and this is the recommended approach for precise queries. When both parameters are provided, the API returns only articles that match both conditions. The category filter narrows the broad topic, while tags drill down to the specific subject.[\/vc_column_text][vc_column_text]\n<h3>What is the difference between\u00a0<em>tag<\/em>\u00a0and <em>q<\/em>\u00a0(keyword search)?<\/h3>\n<p>The\u00a0<strong>q<\/strong>\u00a0parameter performs a free-text search across article titles and body content, it matches any article that literally contains your search term. The\u00a0<strong>tag<\/strong>\u00a0parameter, by contrast, filters by AI-classified metadata, meaning articles are included only if the AI model determined that tag is a core subject of the article. In practice,\u00a0<strong>tag<\/strong>\u00a0is more precise and less noisy: a search for\u00a0<strong>q=Tesla<\/strong>\u00a0might return articles that merely mention Tesla in passing, whereas\u00a0<strong>tag=Tesla<\/strong>\u00a0returns articles where Tesla is a primary topic. Use\u00a0<strong>q<\/strong>\u00a0for broad discovery; use\u00a0<strong>tag<\/strong>\u00a0when topical accuracy matters.[\/vc_column_text][vc_column_text]\n<h3>How accurate is AI-powered news categorization?<\/h3>\n<p>For well-structured, clearly written news articles, modern transformer-based classifiers typically achieve\u00a0<strong>90%+ accuracy<\/strong> on broad categories. Accuracy tends to drop on short articles, opinion pieces, or content that spans multiple topics. AI tagging is generally more reliable than manual keywording at scale because it is consistent and not subject to human fatigue or bias. That said, you should validate classification outputs in any production pipeline that makes automated decisions based on category or tag data, especially for financial, medical, or legal news topics where misclassification has real consequences.[\/vc_column_text][\/vc_column][\/vc_row]\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>Discover News Categorization and Tagging in News APIs, which can make your searches more personalized and efficient.
