# types-aiobotocore-sts — Type annotations for aiobotocore STS 3.9.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 703.5K/mo

## What it is and what it does

This package is a type stub library that adds complete type annotations for the STS service. It is generated using mypy-boto3-builder 8.12.0 and works with static type checkers (mypy, pyright) and IDEs (VSCode, PyCharm, Emacs, Sublime Text) to provide code completion, inline documentation, and type safety for async STS operations.

The package contains type definitions for client methods, service resources, waiters, paginators, and Literal types extracted from AWS shapes. It is designed as a development-time dependency—you can use TYPE_CHECKING guards to avoid including it in production builds. Installation requires only typing-extensions as a runtime dependency.

Use it for:

- Enable IDE autocomplete and type hints when writing async code that calls STS operations.
- Catch type errors in STS client calls during development using mypy or pyright before runtime.
- Document expected argument and return types for STS operations in team codebases.
- Use Literal types from the stubs to enforce valid STS parameter values at type-check time.
- Improve code maintainability by leveraging IDE refactoring tools that depend on accurate type information.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations and IDE autocomplete support for the STS service, enabling static type checking with mypy, pyright, and other tools.

Yes. This is a low-friction, actively maintained type stub with no known vulnerabilities and a permissive MIT license. Install it if you use the STS service and want IDE autocomplete, type checking, or both—it requires only typing-extensions and can be confined to development dependencies via TYPE_CHECKING guards.

## Install

pip install types-aiobotocore-sts
uv add types-aiobotocore-sts
poetry add types-aiobotocore-sts

## Installing types-aiobotocore-sts

Before you install: Low install friction with a single runtime dependency (typing-extensions). Actively maintained with release 12 days ago; repository shows consistent activity.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal obligations.

Quickstart:

pip install 'types-aiobotocore-sts'

from aiobotocore.session import get_session
from types_aiobotocore_sts import STSClient

session = get_session()
async with session.create_client("sts") as client:
    client: STSClient

Requires Python 3.9 or later.

Verify before relying:

- Whether PyCharm performance issues mentioned in the docs have been resolved.
- Compatibility guarantees with versions of the parent package other than 3.9.0.
- Real-world performance impact when used with large codebases in different IDEs.
