### How to create translations using DeepL

```
import AIProxy

/* Uncomment for BYOK use cases */
// let deepLService = AIProxy.deepLDirectService(
// unprotectedAPIKey: "your-deepL-key",
// accountType: .free:
// )

/* Uncomment for all other production use cases */
// let service = AIProxy.deepLService(
// partialKey: "partial-key-from-your-developer-dashboard",
// serviceURL: "service-url-from-your-developer-dashboard"
// )

do {
    let body = DeepLTranslateRequestBody(targetLang: "ES", text: ["hello world"])
    let response = try await service.translateRequest(body: body)
    // Do something with `response.translations`
} catch AIProxyError.unsuccessfulRequest(let statusCode, let responseBody) {
    print("Received \(statusCode) status code with response body: \(responseBody)")
} catch {
    print("Could not create DeepL translation: \(error.localizedDescription)")
}
