# Add Codex to Your App

> Two ways to integrate the Codex crypto data API into your app: the TypeScript SDK or direct GraphQL over HTTP and WebSockets.

| Option 1: *SDK* (recommended) | Option 2: *GraphQL API* |
| - | - |
| Thin wrapper around the API | More customizable depending on your use case |
| Designed to get you started on Codex quickly | Requires more configuration |
| Built-in subscription connection handling | More control over the connections |
| Predefined queries and mutations | Write your own queries |
| Good choice if you *ARE* using Typescript | Good choice if you *ARE NOT* not using Typescript |
