# Railway

Section: [Reference](https://zshot-cli.com/reference/) › [Docker](https://zshot-cli.com/reference/docker/)

Create a [Railway](https://railway.com) service from the **Docker image** source set to `scaleassembly/zshot-server:latest`. Set `ZSHOT_LICENSE` to your key and `ZSHOT_SERVER_TOKEN_AUTH` to a token: Railway serves a public URL, and the API is not built to sit open on the internet. Railway injects `PORT`, which the image binds. Point the health check at `/status` and allow about 1 GB of memory, or 2 GB if it renders video.

## Example

Render through the generated domain with the token:

```sh
curl -H "Authorization: Bearer MY-TOKEN" \
  "https://YOUR-APP.up.railway.app/?url=https://zshot-cli.com/example_assets/hello_zshot/&output_type=png" -o out.png
```
