Parameters

**Table 1** Parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
sources	No	Set of source vertex IDs to be queried	String	-	The value is in the standard CSV format. IDs are separated by commas (,), for example, Alice, Nana.
n	No	Upper limit of the number of enumerated circles that meet the filter criteria	Integer	[1,100000]	100
statistics	No	Whether to export the number of circles that meet the filter criteria	Boolean	true or false	false
batch_number	No	Number of source vertices for batch processing	Integer	[1,1000]	10
output_format	No	Output format	String	vertexId, edgeId, or edgeObject	edgeObject
filters	Yes	Filter criteria. Each element in the array corresponds to a filter.	Json	-	-

**Table 2** filters element formats
Parameter	Mandatory	Description	Type	Value Range	Default Value
operator	No	Direction of the query to be performed at the current layer	String	out, in, or both	out
edge_filter	No	Filter criteria for the current layer. For details, see Table 6 in the Filtered-query API.	Json	-	-
vertex_filter	No	Filter criteria of vertices at the current layer. For details, see Table 6 in the Filtered-query API.	Json	-	-
times	No	Number of layers queried using the same filter criteria	Integer	[1,10]	1

Filter criteria at the first layer are used to filter source vertices. Therefore, only the vertex_filter parameter is valid.
Filter criteria at the last layer are used to filter source vertices.
The circle length ranges from 3 to 10. Therefore, the number of filtering layers is 4 to 11.

**Table 3** response_data parameter description
Parameter	Mandatory	Type	Description
circles	Yes	List	Set of circles found. The format is [[circle1],[circle2], ...]. The circle format is as follows: If output_format is edgeObject, the format is [{"source": sourceId, "target": targetId, "index": edgeIndex}, ...], where sourceId, targetId, and edgeIndex are of the string type. If output_format is edgeId, the format is [sourceId-targetId-edgeIndex,…], where sourceId-targetId-edgeIndex is of the string type. If output_format is vertexId, the format is [vertexId, ...], where vertexId is of the string type.
runtime	Yes	Double	Algorithm running time
n	Yes	Integer	Maximum number of enumerated circles
circle_number	No	Integer	When statistics is set to true, the number of circles that meet filter criteria is displayed.
