1

Add the SDK

Check out Codex Typescript SDK on GitHub or just get right into installation:
npm install @codex-data/sdk
2

Add the API key to your environment variables

Usually these live in your .env file. Add this line and replace xxxxxxxx with your API key:
  CODEX_API_KEY=xxxxxxxx
3

Create an SDK file

Make a new lib/codex-sdk.ts file (or whatever folder/name fits your project) and add:
import { Codex } from "@codex-data/sdk";

export const sdk = new Codex(process.env.CODEX_API_KEY!);
4

Make a request

Now you can import the SDK from other files and make requests. For example:
sdk.queries.token({
  input: {
    address: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c",
    networkId: 56,
  },
})
.then(console.log);
