URI

GET https://{Endpoint}/v3.1/{project_id}/flavors

**Table 1** Path parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID of a tenant in a region. To obtain this value, see Obtaining a Project ID.

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
engine_name	No	String	Database type. The value can be: cassandra, indicating that the instances are of the GeminiDB Cassandra type. mongodb, indicating that the instances are of the GeminiDB Mongo type. influxdb, indicating that the instances are of the GeminiDB Influx type. redis, indicating that the instances are of the GeminiDB Redis type. If this parameter is not transferred, the default value is cassandra.
offset	No	Integer	Index offset. If offset is set to N, the resource query starts from the N+1 piece of data. If action is set to filter, offset is 0 by default, indicating that the query starts from the first piece of data. The offset value must be a number but cannot be a negative number.
limit	No	Integer	Maximum of specifications that can be queried The value ranges from 1 to 100. If this parameter is not transferred, the first 100 pieces of specification information is queried by default.
