# mypy-boto3-cur — Type annotations for boto3 CostandUsageReportService 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 252.2K/mo

## What it is and what it does

This package is a type-stub library that adds type annotations for boto3's CostandUsageReportService (the AWS Cost and Usage Report API). It is generated automatically from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with type checkers (mypy, pyright) and IDEs (VSCode, PyCharm, Emacs, Sublime Text) to provide code completion and catch type errors at development time.

When installed, it allows you to write boto3 code with full type hints, so your IDE can autocomplete method names and parameters, and type checkers can verify your API calls before runtime. It has a single runtime dependency (typing-extensions) and is designed to be lightweight. The package supports Python 3.9 through 3.14 and is actively maintained.

Use it for:

- Enable IDE autocomplete and inline documentation when writing code that calls the AWS Cost and Usage Report API via boto3.
- Catch type errors in boto3 Cost and Usage Report calls using mypy or pyright before deployment.
- Use explicit type annotations for CostandUsageReportServiceClient, paginators, and type definitions in production code.
- Integrate type checking into CI/CD pipelines to validate boto3 Cost and Usage Report API usage across a codebase.
- Reduce development friction when working with boto3 in PyCharm or VSCode by enabling native type discovery.

## Worth the install?

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

Provides type annotations and IDE support for boto3's CostandUsageReportService, enabling type checking and autocomplete in mypy, pyright, VSCode, PyCharm, and other editors.

Yes. If you use boto3's CostandUsageReportService, this package is worth installing to gain IDE autocomplete and type checking. It has low install friction, active maintenance, no known vulnerabilities, a permissive MIT license, and is in the top-15000 tier of PyPI packages by popularity. Install it as part of your development environment or via boto3-stubs[cur] for broader AWS service coverage.

## Install

pip install mypy-boto3-cur
uv add mypy-boto3-cur
poetry add mypy-boto3-cur

## Installing mypy-boto3-cur

Before you install: Low install friction with a single lightweight runtime dependency (typing-extensions). Active maintenance with recent releases; last commit 2026-06-22 and 670 repository stars indicate ongoing support.

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

Quickstart:

pip install mypy-boto3-cur

from boto3.session import Session
from mypy_boto3_cur import CostandUsageReportServiceClient

client: CostandUsageReportServiceClient = Session().client("cur")

Requires Python 3.9 or later; type checking requires mypy, pyright, or a compatible IDE.

Verify before relying:

- Whether PyCharm performance issues mentioned in the description (issue PY-40997) have been resolved since the package was generated.
- Whether the lite variant (boto3-stubs-lite) is recommended for production deployments to reduce memory overhead.
- Actual download volume and user base size to assess community adoption beyond the top-15000 tier classification.
