TrustGraph API Client Library

This package provides Python client interfaces for interacting with TrustGraph services.
TrustGraph is a knowledge graph and RAG (Retrieval-Augmented Generation) platform that
combines graph databases, vector embeddings, and LLM capabilities.

The library offers both synchronous and asynchronous APIs for:
- Flow management and execution
- Knowledge graph operations (triples, entities, embeddings)
- RAG queries (graph-based and document-based)
- Agent interactions with streaming support
- WebSocket-based real-time communication
- Bulk import/export operations
- Configuration and collection management

Quick Start:
    ```python
    from trustgraph.api import Api

    # Create API client
    api = Api(url="http://localhost:8088/")

    # Get a flow instance
    flow = api.flow().id("default")

    # Execute a graph RAG query
    response = flow.graph_rag(
        query="What are the main topics?",
        collection="default"
    )
    ```

For streaming and async operations:
    ```python
    # WebSocket streaming
    socket = api.socket()
    flow = socket.flow("default")

    for chunk in flow.agent(question="Hello"):
        print(chunk.content)

    # Async operations
    async with Api(url="http://localhost:8088/") as api:
        async_flow = api.async_flow()
        result = await async_flow.id("default").text_completion(
            system="You are helpful",
            prompt="Hello"
        )
    ```
