OpenAPI Spec

Download the raw OpenAPI/Swagger specification. AI tools and code generators can consume this directly.

Post-Production API Coming Soon

AI-powered dialogue enhancement, delivery format mastering, sidechain ducking, and loudness compliance for film, TV, streaming, advertising, and podcasting. Available now in the C++ SDK.
Stem Separation & Vocal Mixing API

Split a mix. Mix a vocal over a beat. Master it.

Turn any finished stereo track back into controllable parts, or mix a recorded vocal directly against a licensed beat — then master the result. /recombine works with or without /separate.

Input Stereo Mix Any WAV / FLAC / MP3
POST /separate 4 Stems
VOCALS DRUMS BASS OTHER
75 credits on success
POST /recombine Mix & Master Free to submit + preview
Output Mastered WAV 250 credits once
Read the Tutorial 325 credits end-to-end ยท $3.25 (Small) / $2.60 (Large)

Already have a vocal and a beat? Skip separation entirely — call /recombine directly with vocalStemURL + backingStemURL for just 250 credits. See the Vocal + Beat Mix & Master quickstart.
