## What it is and what it does

This package is a stub-only type annotation library for boto3's MarketplaceCatalog service, generated automatically from boto3 version 1.43.62 using mypy-boto3-builder 8.12.0. It enables static type checking and IDE code completion when working with AWS MarketplaceCatalog API calls through boto3, without adding runtime behavior—it only provides type information for development-time tooling.

You install it alongside boto3 in your development environment, and IDEs like VSCode, PyCharm, Emacs, and Sublime Text will immediately offer autocomplete and type hints for MarketplaceCatalog client methods, paginators, and type definitions. It also works with command-line type checkers like mypy and pyright. The package has no runtime dependencies beyond typing-extensions and is safe to exclude from production deployments using TYPE_CHECKING guards.

Use it for:

- Enable IDE autocomplete and inline documentation for MarketplaceCatalog API calls in VSCode or PyCharm.
- Catch type errors in boto3 MarketplaceCatalog code before runtime using mypy or pyright.
- Reduce boilerplate by letting your IDE infer argument types and return types for client methods.
- Provide explicit type hints for MarketplaceCatalog paginators and service resource types in typed codebases.
- Integrate type checking into CI/CD pipelines for AWS SDK code without manual annotation.

## Worth the install?

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

Provides type annotations and IDE autocompletion support for boto3's MarketplaceCatalog service, compatible with mypy, pyright, VSCode, PyCharm, and other type-aware tools.

Yes, if you use boto3's MarketplaceCatalog service and want IDE autocompletion or static type checking. Install friction is minimal, maintenance is active, and the MIT license has no restrictions. The only gotcha is PyCharm performance on Literal overloads—documented workarounds exist. For most Python 3.9+ projects using MarketplaceCatalog, this is a straightforward win.

## Install

pip install mypy-boto3-marketplace-catalog
uv add mypy-boto3-marketplace-catalog
poetry add mypy-boto3-marketplace-catalog

## Installing mypy-boto3-marketplace-catalog

Before you install: Low friction install with a single lightweight runtime dependency (typing-extensions). Actively maintained with recent releases; the package is generated automatically and follows boto3 version releases closely.

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

Quickstart:

pip install mypy-boto3-marketplace-catalog

from boto3.session import Session
from mypy_boto3_marketplace_catalog import MarketplaceCatalogClient

client: MarketplaceCatalogClient = Session().client("marketplace-catalog")

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Whether type coverage is complete for all MarketplaceCatalog API operations and edge cases.
- Performance impact on IDE responsiveness when used with PyCharm (documentation mentions potential slowness).
- Whether the package works correctly with boto3-stubs-lite as a lighter alternative.
