## What it is
CargoBay is an Objective-C library that wraps Apple's StoreKit framework to simplify In-App Purchases on iOS. It provides block-based product requests, payment queue observation, and secure receipt and transaction verification.

## Use cases
- verify in-app purchase receipts against Apple's servers
- fetch StoreKit product information with a block-based API
- observe payment queue transaction updates without delegate boilerplate
- deduplicate StoreKit transactions automatically
- add in-app purchases to an iOS app with less boilerplate

## When to choose
- you maintain a legacy Objective-C iOS app using StoreKit and want simpler receipt verification
- you prefer block-based callbacks over StoreKit's delegate pattern

## When to avoid
- starting a new project - the library is explicitly unmaintained since 2021
- you need Swift-first or modern StoreKit 2 support
- you need guaranteed compatibility with current iOS SDKs
