Quick Start

import asyncio
from modal_agents_sdk import query

async def main():
    async for message in query("What is 2 + 2?"):
        print(message)

asyncio.run(main())

Basic Usage: `query()`

`query()` is an async function for querying Claude in a Modal sandbox. It returns an `AsyncIterator` of response messages.

from modal_agents_sdk import query, ModalAgentOptions, AssistantMessage, TextBlock
import modal
