Wondercraft Audio Generation API

info:
  title: Wondercraft Public Account Audio Generation API
  description: 'The Wondercraft Public API creates audio content - podcasts, audio ads, meditations, and audiobooks - from an AI-generated or user-supplied script. Generation is asynchronous: a create request returns a job_id, which is then polled for completion and an MP3 download URL. Voices and background music are referenced by IDs copied from the Wondercraft platform. API access requires a paid plan.'
