Melange API Specification

<<TableOfContents()>>

General Information

The Melange API is implemented using a RESTful web service interface.

• All GET /resources accepts 'limit' and 'marker' params. If these params are not passed default limit is applied.
• If POST or PUT on a resource doesn't send mandatory params, API returns '400 Bad Request' response.

Request/Response Types

• The Melange API supports both the JSON and XML data serialization formats.
• The request format is specified using the Content-Type header and is required for operations that have a request body.
• The response format can be specified in requests using either the Accept header or adding an .xml or .json extension to the request URI.
• If no response format is specified, JSON is the default.
• If conflicting formats are specified using both an Accept header and a query extension, the query extension takes precedence.

To Be Done:

• Add 'self' and 'bookmark' links in resource details.
• Versions atom feed
• API to list all IPs by an instance_id
