  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.
