GET /v1/sound-effects/:id/license

Download the generation certificate for one of your sound effects — the same formal, single-page PDF as track certificates, issued by Riku AI LLC and confirming the sound effect was generated by you on Finetuning.

One certificate covers the whole sound-effect request; the title and duration on the certificate come from the request's first clip.
