Azure Cosmos DB is a a globally distributed multi-model databases that supports the document, graph, and key-value data models. The content in this section is for creating, querying, and managing document resources using the DocumentDB API via REST.
The Azure Cosmos DB REST API provides programmatic access to Azure Cosmos DB resources to create, query, and delete databases, document collections, and documents. To perform operations on Azure Cosmos DB resources, you send HTTPS requests with a supported method: GET, POST, PUT, or DELETE to an endpoint that targets a resource collection or a specific resource. This section contains information about working with resources by using the REST API.
The follow video gives a great introduction to Azure Cosmos DB REST APIs.
