As a developer, finding the right API for your project can be a game-changer. A well built API can significantly reduce your project timeline, make your life easier, and result in a more robust result. APIs are the foundation of a composable architecture and reason small development teams can build amazing highly complex applications. However, not all APIs are created equal. Some require a significant investment upfront, some are open-source allowing you to test it locally, while others offer free sign-ups or trials to help you test the waters. In this blog post, we will be discussing production APIs for developers and for each category offer the leading SaaS and open-source alternative.

## 4. Ecommerce

Ecommerce feels like a manageable project until you being diving into the weeds of product bundles, promotions, and payments. Ecommerce represents the classic ninety-ninety rule, where the first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the _other_ 90 percent of the development time. This is why it's best to leverage an ecommerce solution instead of building it yourself.

#### Commerce Layer
