marona 0.2.16

Official Python client SDK for Marona-compatible AI runtimes and Hub integrations.

marona

Official Python client for Marona-compatible AI runtimes and Hub integrations.

Use marona to build web apps, mobile backends, WhatsApp bots, desktop apps, devices, smart glasses, and agents that need one API for online, offline, and hybrid AI execution.

Install

pip install marona

Complete Example

This example shows the normal flow for a developer application:

1. Create a Marona client.
2. Sync Hub metadata into the local cache.
3. Connect approved Hub apps by app ID.
4. Send a user message through the runtime.
5. Print the final assistant response.

The optional developer role controls app behavior.

        await marona.sync(
            interface="api",
            identity_token=identity_token,
        )

                },
                {
                    "role": "user",
                    "content": [
                        {
                            "type": "input_text",
                            "text": "What teams are playing in this image?",
                        },
                        {
                            "type": "input_image",
                            "image_url": "https://api.nga.gov/iiif/a2e6da57-3cd1-4235-b20e-95dcaefed6c8/full/!800,800/0/default.jpg",

                            "filename": "document.pdf",

                            "detail": "high",
                        },
                    ],
                }
            ],
            interface="api",
            identity_token=identity_token,
            tools=tools,
        )

        print(response.text)


asyncio.run(main())

Run it:

export MARONA_API_KEY="mrn_live_..."
python app.py

Pair A User

Use pairing when an interface needs to become the same user across web, mobile, WhatsApp, wearables, or another client surface.

async with Marona(api_key=os.environ["MARONA_API_KEY"]) as marona:
    pairing = await marona.start_pairing(
        interface="web",
        device_name="Customer web chat",
    )

    print(pairing.display_code)
    print(pairing.whatsapp_url)

    status = await marona.pairing_status(pairing.pairing_id)
    print(status.status)

After the user confirms pairing, store the returned identity token and pass it to marona.client(...).

Online, Offline, And Hybrid Modes

Choose one runtime mode for the client:

• online: use online runtime and online app routes.
• offline: use only local cache, local/private models, and installed offline-capable app targets.
• hybrid: try local/private execution first, then use online runtime when allowed.

Apps also declare one availability mode:

• online: online only.
• offline: offline only.
• hybrid: online and offline capable.

Hybrid is a single mode. Do not declare online + offline + hybrid; declare hybrid.

Hybrid Or Offline With A Local/Private Model

Register a local or private model endpoint once, then use it as the default for hybrid or offline execution.

async with Marona(api_key=os.environ["MARONA_API_KEY"], mode="hybrid") as marona:
    await marona.sync(interface="api")

    marona.models.register(
        name="office-model",
        endpoint="http://localhost:9379",
    )
    marona.models.use("office-model")

    tools = await marona.hub.connect(["sda-books", "zimsec"], adapter="tools")

    response = await marona.client(
        input=[
            {
                "role": "user",
                "content": [
                    {
                        "type": "input_text",
                        "text": "Summarize the chapter about faith.",
                    }
                ],
            }
        ],
        interface="desktop",
        tools=tools,
    )

    print(response.text)

In offline mode, Marona never calls public cloud runtime. If a model or an offline-capable app target is missing, the client returns a clear offline error.

Interface Names

interface identifies the client surface making the request. Standard values:

• api
• web
• mobile_app
• desktop
• whatsapp

Future devices can use custom lowercase slugs such as smart_glasses, vehicle_console, or kiosk.
