Blazar REST API v2 (deprecated)¶

1 General API information¶

This section contains base information about the Blazar REST API design, including operations with different Blazar resource types and examples of possible requests and responses. Blazar supports JSON data serialization format, which means that requests with non empty body have to contain “application/json” Content-Type header or it should be added “.json” extension to the resource name in the request.

This should look like the following:

GET /v2/leases.json

or

GET /v2/leases
Accept: application/json

2 Leases¶

Description

Lease is the main abstraction for the user in the Blazar case. Lease means some kind of contract where start time, end time and resources to be reserved are mentioned.
