Request Parameters

**Table 1** Request body parameters
Parameter	Mandatory	Type	Description
algorithmName	Yes	String	Algorithm name. Available values are as follows (algorithm names you can call): pagerank personalrank kcore k_hop shortest_path all_shortest_paths filtered_shortest_path sssp shortest_path_of_vertex_sets n_paths closeness label_propagation louvain link_prediction node2vec realtime_recommendation common_neighbors connected_component degree_correlation triangle_count cluster_coefficient common_neighbors_of_vertex_sets all_shortest_paths_of_vertex_sets filtered_circle_detection filtered_all_pairs_shortest_paths filtered_all_shortest_paths filtered_n_paths
parameters	Yes	Object	Algorithm parameters. For details, see the parameter description of each algorithm.

**Table 2** New Body parameters of version 2.1.7
Parameter	Mandatory	Type	Description
executionMode	No	String	sync: synchronous async: asynchronous The default value is async. Supported algorithms are as follows (algorithm names you can call): k_hop shortest_path all_shortest_paths filtered_shortest_path shortest_path_of_vertex_sets n_paths realtime_recommendation
offset	No	Integer	Synchronization result offset. The default value is 0. NOTE: This parameter is available when executionMode is sync. Supported algorithms are as follows (algorithm names you can call): k_hop shortest_path all_shortest_paths shortest_path_of_vertex_sets n_paths realtime_recommendation filtered_all_pairs_shortest_paths filtered_all_shortest_paths
limit	No	Integer	Maximum number of returned synchronization results. The maximum value is 100000. The default value is 100000. NOTE: This parameter is available when executionMode is sync. Supported algorithms are as follows (algorithm names you can call): k_hop shortest_path all_shortest_paths shortest_path_of_vertex_sets n_paths realtime_recommendation filtered_all_pairs_shortest_paths filtered_all_shortest_paths

**Table 3** New Body parameters of version 2.2.4
Parameter	Mandatory	Type	Description
vertex_filter	No	Object	Filter criteria for the vertices on a path. Supported algorithms are as follows (algorithm names you can call): filtered_shortest_path filtered_all_pairs_shortest_paths filtered_all_shortest_paths For details about the format, see Table 6 in "Filtered-query API".
edge_filter	No	Object	Filter criteria for the edges (relationships) on a path. Supported algorithms are as follows (algorithm names you can call): filtered_shortest_path filtered_all_pairs_shortest_paths filtered_all_shortest_paths For details about the format, see Table 6 in "Filtered-query API".
filters	No	Object	Filter criteria. Each element in the array corresponds to a filter. This parameter applies only to filtered circle detection. For details about the format, see filters element formats. Supported algorithms: filtered_n_paths

Example Response

Algorithms are executed based on input parameters. You can call Querying Job Status and Execution Results to use the job_id returned by the algorithm to obtain the algorithm execution result.

Status code: 200

Example response for a successful request

{
    "data": {

   "outputs": {
           $response_data //Result of each algorithm. The results vary with the algorithm.
           "runtime": 1.365867,
           "data_return_size": 3,
           "data_offset": 0,
           "data_total_size": 100
    }
  },
  "status": "complete"
}

response_data indicates the result of each algorithm. The results vary with algorithms.

Status code: 400

Example response for a failed request

Http Status Code: 400
{
"errorMessage":"Running algorithm [XXXX] error: YYYYYYYYY!",
"errorCode":"GES.8301"
}

Response Parameters

**Table 4** Response body parameters
Parameter	Type	Description
errorMessage	String	System prompt. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error message.
errorCode	String	System prompt. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
status	String	Returned job status for a successful query. Possible values are waiting, running, and complete. This parameter is left blank when the query fails.
data	Object	Algorithm execution result. This parameter is left blank when the query fails.
