Modern AWS SDK for Python — async-native, fully typed, and generated from official Smithy models.

Installation

Each service is distributed as its own package (e.g. aws-sdk-s3, aws-sdk-ec2).

Features

• async and sync — Use the same API for both async and sync code, with support for asyncio and trio.
• WASM support — Runs in WASM environments via Pyodide.
• typed and documented — Fully typed and documented for a better developer experience.
• simple inputs — No need to import separate parameter classes; nested inputs are fully typed via TypedDicts.
• generated from Smithy models — The SDK is generated from the official Smithy models describing AWS APIs, ensuring accuracy and consistency.
• zero runtime overhead — Codegen produces dedicated serialization and deserialization code for each operation, avoiding reflection.
• interchangeable input/output — Input and output types use the same TypedDicts, so you can pass a response directly as input when appropriate.
• built on zapros — A modern HTTP client for Python that abstracts HTTP semantics from the transport implementation.

Usage

from aws_sdk_s3 import S3Client

with S3Client() as s3:
    response = s3.create_bucket("capo")
    print(response)

Async:

from aws_sdk_s3 import AsyncS3Client

async def main():
    async with AsyncS3Client() as s3:
        response = await s3.create_bucket("capo")
        print(response)

See the README for each service under the services/ directory for detailed usage including pagination, waiters, and error handling.
