TrustGraph Graph RAG API

This presents a prompt to the Graph RAG service and retrieves the answer. This makes use of a number of the other APIs behind the scenes: Embeddings, Graph Embeddings, Prompt, TextCompletion, Triples Query.

Request/response

Request

The request contains the following fields:

• query: The question to answer

Response

The response contains the following fields:

• response: LLM response

REST service

The REST service accepts a request object containing the query field. The response is a JSON object containing the response field.

e.g.

Request:

{
    "query": "What does NASA stand for?"
}

Response:

{
    "response": "National Aeronautics and Space Administration"
}

Websocket

Requests have a request object containing the query field. Responses have a response object containing response field.

e.g.

Request:

{
    "id": "blrqotfefnmnh7de-14",
    "service": "graph-rag",
    "flow": "default",
    "request": {
        "query": "What does NASA stand for?"
    }
}

Response:

{
    "id": "blrqotfefnmnh7de-14",
    "response": {
        "response": "National Aeronautics and Space Administration"
    },
    "complete": true
}

Pulsar

The Pulsar schema for the Graph RAG API is defined in Python code here:

https://github.com/trustgraph-ai/trustgraph/blob/master/trustgraph-base/trustgraph/schema/retrieval.py

Default request queue: non-persistent://tg/request/graph-rag

Default response queue: non-persistent://tg/response/graph-rag

Request schema: trustgraph.schema.GraphRagRequest

Response schema: trustgraph.schema.GraphRagResponse

Pulsar Python client

The client class is trustgraph.clients.GraphRagClient
