  title: Shotstack Create Templates API
  description: Shotstack is a cloud video-editing platform that renders video, image, and audio assets from a JSON edit specification. This document covers the Edit API (render and templates), the Ingest API (source assets), the Serve API (asset hosting and delivery), and the Create API (AI-generated assets). All endpoints authenticate with an `x-api-key` header. Each API is available in a `v1` (production) and `stage` (sandbox) environment.
