# alibabacloud-openapi-util — Aliyun Tea OpenApi Library for Python

License: permissive · Maintenance: active · Downloads: 4.5M/mo

## What it is and what it does

This package is a utility library for working with Alibaba Cloud's OpenAPI services in Python. It provides helper functions for constructing, signing, and serializing API requests to Alibaba Cloud endpoints, abstracting away common boilerplate needed when calling cloud services. The library depends on alibabacloud-tea-util for core utilities and cryptography for request signing operations.

It is designed as a low-level building block, typically used by higher-level Alibaba Cloud SDKs rather than directly by application code. The package has been actively maintained since 2020, with recent updates, and carries no known security vulnerabilities. Installation is straightforward with minimal dependencies.

Use it for:

- Building custom Alibaba Cloud API clients when existing SDKs don't cover your use case
- Integrating Alibaba Cloud services into applications that need low-level OpenAPI request control
- Handling request signing and serialization for Alibaba Cloud endpoints in middleware or gateway code
- Extending or wrapping Alibaba Cloud API calls with custom logic or monitoring

## Worth the install?

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

Provides utility functions for constructing and handling OpenAPI requests to Alibaba Cloud services, wrapping common operations like request signing and serialization.

Yes, if you are building applications that call Alibaba Cloud OpenAPI services and need the underlying request utilities. The package is actively maintained, has no known vulnerabilities, and carries a permissive Apache 2.0 license. However, verify first whether a higher-level Alibaba Cloud SDK already covers your use case, as this is primarily a low-level utility library.

## Install

pip install alibabacloud-openapi-util
uv add alibabacloud-openapi-util
poetry add alibabacloud-openapi-util

## Installing alibabacloud-openapi-util

Before you install: Low friction install with only two runtime dependencies (alibabacloud-tea-util and cryptography). Active maintenance with a recent release in January 2026 and last commit in July 2026.

License in practice: Licensed under Apache License 2.0 (permissive), allowing commercial and private use with minimal restrictions beyond attribution and liability disclaimers.

Quickstart:

pip install alibabacloud_openapi_util

from alibabacloud_openapi_util import Client
# Use Client methods for OpenAPI request construction

Verify before relying:

- What specific OpenAPI operations or request types this utility supports beyond basic signing and serialization
- Whether this package is intended for direct use or primarily as a dependency for higher-level Alibaba Cloud SDKs
- Performance characteristics or rate-limiting behavior when handling large volumes of requests
