Getting Started

Installation

pip install capo-route-53

Usage

from capo_route_53 import AsyncRoute53Client


async def main():
    async with AsyncRoute53Client() as route53:
        # Example: call the activate_key_signing_key operation
        response = await route53.activate_key_signing_key()
        print(response["change_info"])

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_route_53 import AsyncRoute53Client


async def main():
    async with AsyncRoute53Client() as route53:
        # Example: paginate over list_cidr_blocks
        async for item in route53.iter_list_cidr_blocks():
            print(item)

Error Handling

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

from capo_route_53 import AsyncRoute53Client
from capo_route_53.error import ConcurrentModification


async def main():
    async with AsyncRoute53Client() as route53:
        try:
            await route53.activate_key_signing_key()
        except ConcurrentModification 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_route_53 import AsyncRoute53Client


async def main():
    async with AsyncRoute53Client() as route53:
        # Default: 3 attempts for every operation
        response = await route53.activate_key_signing_key()

        # Override per operation
        response = await route53.activate_key_signing_key(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await route53.activate_key_signing_key(config_overrides={"retry_max_attempts": 1})
