+#### API
+
+Data Contract CLI can test APIs that return data in JSON format. 
+Currently, only GET requests are supported.
+
+##### Example
+
+datacontract.yaml
+```yaml
+servers:
+  api:
+    type: "api"
+    location: "https://api.example.com/path"
+    delimiter: none # new_line, array, or none (default)
+
+models:
+  my_object: # corresponds to the root element of the JSON response
+    type: object
+    fields:
+      field1: 
+        type: string
+      fields2: 
+        type: number
+```
+
+##### Environment Variables
+
+| Environment Variable                    | Example          | Description                                       |
+|-----------------------------------------|------------------|---------------------------------------------------|
+| `DATACONTRACT_API_HEADER_AUTHORIZATION` | `Bearer <token>` | The value for the `authorization` header. Optional. |
+
+
 #### Local
 
 Data Contract CLI can test local files in parquet, json, csv, or delta format.
