A better way to work with APIs.

The old way

Find a client library: A good one is golden, however most are outdated or simply unavailable in your app’s programming language.
Write your own client library: Takes a lot of effort and must be updated when the API changes. You should be focused on your app, anyway.
Read API data as dynamic, untyped values: This is an unpleasant way to program and leaves your app vulnerable to API changes.

With quicktype

Generate your client libraries: Given sample API responses, quicktype will generate an easy-to-use client library in your app’s language.
Spend more time on your app: quicktype can regenerate types when APIs change, so you can simply update affected app code, if any.
Access strongly typed API data with help: Get more out of your editor or IDE (autocomplete, refactoring) when working with typed API data.
