Speech Analytics API returning partial transcript for long calls

Is there a clean way to retrieve the full conversation transcript for calls exceeding 15 minutes using the Speech and Text Analytics API? The /api/v2/analytics/speech/text/queries endpoint consistently truncates the output after 10k characters, returning this error:

Error: Transcript length exceeds maximum allowed size for single query result.

Is there a pagination token or offset parameter I’m missing in the request body, or should I be chaining multiple conversationId queries?
