# Mosio REST API ## Pages - [Mosio REST API](https://docs.mosio.me/api/index.md) — Render short videos from Mosio templates or from your own HTML compositions. Every request needs an API key in the `x-api-key` header. Create one in the dashboard under **API key**. A key belongs to one workspace: it sees only that workspace's videos and spends that workspace's credits. Videos render in a queue. Creating one returns its id straight away; poll `GET /v1/videos/{id}` until `status` is `done`, then download `output_url`. ## Sections - [Compositions](https://docs.mosio.me/api/compositions/llms.txt) - [Tags](https://docs.mosio.me/api/tags/llms.txt) - [Videos](https://docs.mosio.me/api/videos/llms.txt)
