​

Store your API key in an environment variable.
export WALLETSUITE_API_KEY="your_api_key"
If you are using an .env file, add:
WALLETSUITE_API_KEY=your_api_key

​
Initialize the Client

Create a client instance and pass your API key and environment.
import { WalletSuiteSDK } from "@walletsuite/wallet-sdk"

const sdk = new WalletSuiteSDK({
  apiKey: process.env.WALLETSUITE_API_KEY!,
  env: "prod",
})
Notes:
  • The SDK automatically sends the X-API-KEY header on every request
  • All requests are scoped to your organization

​
Make Your First API Call

Call an endpoint from the SDK client. The exact method names depend on the SDK version, but usage follows this pattern.
async function main() {
  const result = await sdk.api.getLatestBlocks("ethereum");
  console.log(JSON.stringify(result, null, 2));
}

main().catch(console.error);
