# mypy-boto3-marketplace-discovery — Type annotations for boto3 MarketplaceDiscovery 1.43.66 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 112.3K/mo

## What it is and what it does

This package is a type-stub library that adds static type annotations to boto3's MarketplaceDiscovery service. It is generated automatically using mypy-boto3-builder 8.12.0 and enables IDEs and type checkers to understand boto3 API calls, providing code completion and catching type errors before runtime.

The package works by installing alongside boto3 and integrating with type checkers (mypy, pyright) and IDEs (VSCode with Pylance, PyCharm, Emacs, Sublime Text). It covers client methods, paginators, waiters, and service resource types for the MarketplaceDiscovery API. Installation is straightforward via pip, either as a standalone package or as part of the boto3-stubs bundle. The package has no production runtime cost—it is a stubs-only library marked as such in its classifiers.

Use it for:

- Enable IDE autocomplete and inline documentation for MarketplaceDiscovery API calls in VSCode or PyCharm.
- Catch boto3 API misuse (wrong parameter names, types) at development time using mypy or pyright.
- Provide type hints for paginator and waiter objects when iterating over MarketplaceDiscovery results.
- Support type-safe boto3 code in projects that enforce static type checking in CI/CD pipelines.

## Worth the install?

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

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

Yes, if you use boto3's MarketplaceDiscovery service and want IDE support or static type checking. Install friction is minimal, maintenance is active, and the MIT license carries no restrictions. The only caveat is PyCharm users may experience performance issues with the full stubs; in that case, boto3-stubs-lite is recommended as an alternative.

## Install

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

## Installing mypy-boto3-marketplace-discovery

Before you install: Low install friction with a single runtime dependency (typing-extensions). Actively maintained with releases within the past week; repository shows 670 stars and recent commits.

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

Quickstart:

# Install with boto3-stubs
python -m pip install 'boto3-stubs[marketplace-discovery]'

# Use in code
from boto3.session import Session
from mypy_boto3_marketplace_discovery import MarketplaceDiscoveryClient

client: MarketplaceDiscoveryClient = Session().client("marketplace-discovery")

Requires boto3 to be installed separately; type checking requires a compatible tool like mypy, pyright, or an IDE with type-checking support.

Verify before relying:

- Performance impact in PyCharm with full boto3-stubs (documentation mentions potential slowness with Literal overloads).
- Whether the lite variant (boto3-stubs-lite) provides equivalent type coverage for MarketplaceDiscovery.
