+### AlchemyData News
+Use the [AlchemyData News][alchemyData_news] service to provide news and blog content enriched with natural language processing to allow for highly targeted search and trend analysis. Now you can query the world's news sources and blogs like a database.
+
+#### Getting News
+AlchemyData News indexes 250k to 300k English language news and blog articles every day with historical search available for the past 60 days. You can query the News API directly with no need to acquire, enrich and store the data yourself - enabling you to go beyond simple keyword-based searches. You can request which fields to return and filter fields by string. All available fields can be accessed using Fields constants in the AlchemyData News Data Model.
+
+```
+private AlchemyAPI m_AlchemyAPI = new AlchemyAPI();
+
+void Start()
+{
+	string[] returnFields = {Fields.ENRICHED_URL_ENTITIES, Fields.ENRICHED_URL_KEYWORDS};
+	Dictionary<string, string> queryFields = new Dictionary<string, string>();
+	queryFields.Add(Fields.ENRICHED_URL_RELATIONS_RELATION_SUBJECT_TEXT, "Obama");
+	queryFields.Add(Fields.ENRICHED_URL_CLEANEDTITLE, "Washington");
+
+	if (!m_AlchemyAPI.GetNews(OnGetNews, returnFields, queryFields))
