 A sdk for AlchemyAPI using Python
+
+
+## AlchemyAPI ##
+
+AlchemyAPI offers artificial intelligence as a service. We teach computers to learn how to read and see, and apply our technology to text analysis and image recognition through a cloud-based API. Our customers use AlchemyAPI to transform their unstructured content such as blog posts, news articles, social media posts and images into much more useful structured data. 
+
+AlchemyAPI is a tech startup located in downtown Denver, Colorado. As the world’s most popular text analysis service, AlchemyAPI serves over 3.5 billion monthly API requests to over 35,000 developers. To enable our services, we use artificial intelligence, machine learning, neural networks, natural language processing and massive-scale web crawling. Our technology powers use cases in a variety of industry verticals, including social media monitoring, business intelligence, content recommendations, financial trading and targeted advertising.

+## API Key ##
