Getting Started

Installation

pip install capo-qbusiness

Usage

from capo_qbusiness import AsyncQBusinessClient


async def main():
    async with AsyncQBusinessClient() as q_business:
        # Example: call the associate_permission operation
        response = await q_business.associate_permission()
        print(response["statement"])

Pagination

Some operations in this SDK support pagination. If the operation supports pagination it will have an iter_ prefixed method that returns an async iterator.

from capo_qbusiness import AsyncQBusinessClient


async def main():
    async with AsyncQBusinessClient() as q_business:
        # Example: paginate over get_chat_controls_configuration
        async for item in q_business.iter_get_chat_controls_configuration():
            print(item)

Streaming Request

Some operations accept a streaming request body. Pass an async iterator of bytes chunks, or the whole body as bytes, for the streaming parameter.

from capo_qbusiness import AsyncQBusinessClient


async def main():
    async with AsyncQBusinessClient() as q_business:
        # Example: call chat with a streaming request body
        async def chunks():
            yield b'Hello, World!'

        response = await q_business.chat(input_stream=chunks())
        print(response)

        # Or pass the whole body as bytes
        response = await q_business.chat(input_stream=b'Hello, World!')
        print(response)

Error Handling

The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.

from capo_qbusiness import AsyncQBusinessClient
from capo_qbusiness.error import AccessDeniedException


async def main():
    async with AsyncQBusinessClient() as q_business:
        try:
            await q_business.associate_permission()
        except AccessDeniedException as e:
            print(f"Error: {e}")
            print(e.data)  # additional error data

Retrying

The SDK retries failed operations automatically. Retry behaviour follows the Smithy specification: errors are retried based on their is_retryable and is_throttling_error attributes. Throttling errors use a longer base delay. Network-level failures (connection errors and timeouts) are also retried. Non-retryable errors, such as client errors without the @retryable trait, are raised immediately without further attempts.

The number of attempts defaults to 3 and can be changed at the client level via retry_max_attempts, or per call via config_overrides.

from capo_qbusiness import AsyncQBusinessClient


async def main():
    async with AsyncQBusinessClient() as q_business:
        # Default: 3 attempts for every operation
        response = await q_business.associate_permission()

        # Override per operation
        response = await q_business.associate_permission(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await q_business.associate_permission(config_overrides={"retry_max_attempts": 1})
