No published rate for this endpoint yet, so it cannot be run — an unpriced model is refused rather than billed at a guess.

Not on the gateway yet: kie/google/gemini-3-1-flash-tts has no price in the billing table, so this request is refused with unpriced_model rather than run. The snippet is here so the shape is clear the day it opens.

Or copy the request and run it with your RenderHour API key — the one in your profile.
