https://api.musicapi.ai/api/v1/sonic/create

Unified endpoint for creating, extending, and covering music. The operation is determined by the task_type parameter.

Credits cost: 20 per generation call (create_music, description mode, cover_music, persona_music) on every model. extend_music, remaster, add_vocals and add_instrumental cost 15, and concat_music costs 2. persona_music with max_mode: true costs 40.

Suno's v6 release on 2026-09-09 did not change any mv value here — see Sonic Instructions and the API Changelog.
