**Table 1** parameters parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
k	Yes	Number of cores The algorithm returns vertices whose number of cores is greater than or equal to k.	Integer	Greater than or equal to 0	-

**Table 2** response_data parameter description
Parameter	Type	Description
coreness	List<Map<String,Integer>>	Coreness value (coreness ≥ k) of each vertex. The format is as follows: [{vertexId:corenessValue},...], where vertexId is of the string type. corenessValue is of the integer type.
