Description

We need access to the x-request-id header to debug API requests with the OpenAI team, as described in the official docs:
👉 https://platform.openai.com/docs/api-reference/debugging-requests

Although x-request-id can be obtained when using:

OpenAIClientAsync.withRawResponse()

We are using SSE streaming in our project, below is example code:

OpenAIClientAsync currentClient = OpenAIOkHttpClientAsync.builder().build();

currentClient.responses().createStreaming(params)
    .subscribe(event -> {
        // business logic
    })
    .onCompleteFuture()
    .thenAccept(result -> {
        // handle completion
    })
    .exceptionally(ex -> {
        // handle error
        return null;
    });

Feature request

Please provide a way to access the x-request-id header in SSE streaming responses (e.g., via callback, metadata, or event property).
This would make debugging and support much easier without requiring a full switch to withRawResponse().
