HTTP bindings

Method Name	Method	Route	Body	Response
ProcessGraphRAGQuery	POST	/v1/graphrag-query	GraphRAGQueryRequest	GraphRAGQueryResponse
HealthCheck	GET	/v1/health	HealthCheckRequest	HealthCheckResponse

ProcessGraphRAGQuery

Process a GraphRAG query (either global or local or unified) and return the retrieval result.

Input Body: GraphRAGQueryRequest
Output: GraphRAGQueryResponse

HealthCheck

Health check endpoint to verify service availability.

Input Body: HealthCheckRequest
Output: HealthCheckResponse

GraphRAGQueryRequest

A request to perform a GraphRAG query.

Field	Type	Label	Description
query	string		The query string for retrieval, e.g. "What is the capital of France?"
level	int32		The desired level for community schema retrieval (if applicable). Defaults to 2 if not provided.
query_type	QueryType		The type of query to perform: GLOBAL or LOCAL or UNIFIED. If not specified, defaults to GLOBAL.
provider	Provider		The embedding/completion provider to use. If not specified, defaults to OPENAI.
response_type	string		Instructions passed to the LLM to specify a custom response generation style (e.g "Short answer", "Multiple paragraphs", "Sarcastic answer", etc.). If not specified, uses the default response types specified by the Local & Global & Unified Query Parameters.
include_metadata	bool		Whether to include metadata in the response. If not specified, defaults to false.

GraphRAGQueryResponse

The response from a GraphRAG query.

Field	Type	Label	Description
result	string		The textual result of the retrieval process.
metadata	string		Optional additional metadata about the result, if needed in the future.

HealthCheckRequest

Empty request for health check as per standard health check patterns.

HealthCheckResponse

Health check response indicating the current server status.

Field	Type	Label	Description
status	string		Current health status (e.g. "OK", "BAD")
message	string		Optional detailed message about health status.

Provider

Enumeration of provider types.

Name	Number	Description
OPENAI	0
OLLAMA	1
TRITON	2

QueryType
