Pull request overview

This PR updates the SDK core Response wrapper to eagerly parse the underlying HTTP response body as JSON during initialization, extracting Result and ResponseMetadata.

Changes:

• Add JSON parsing when constructing Response.
• Populate Response.result and Response.metadata directly from parsed payload.

PEP8: add a blank line after the import and before the class definition (top-level class definitions should be separated by two blank lines).

Suggested change

	import json
	import json

ResponseMetadata error handling is skipped here: if the JSON contains a ResponseMetadata.Error block, Response will still populate result/metadata and no ApiException is raised. To keep behavior consistent with DeserializedResponseInterceptor.deserialize (which raises on Error / missing ResponseMetadata), consider checking ResponseMetadata.Error and raising the same ApiException (or deferring JSON parsing to that interceptor).

Suggested change

	self.result = data.get("Result")
	self.metadata = data.get("ResponseMetadata")
	metadata = data.get("ResponseMetadata")
	if metadata is None:
	raise ValueError("Missing ResponseMetadata in HTTP response.")
	error = metadata.get("Error") if isinstance(metadata, dict) else None
	if error:
	raise ValueError(f"API returned error in ResponseMetadata: {error}")
	self.metadata = metadata
	self.result = data.get("Result")
