## Global patterns

Every command accepts long and short forms for input and output paths:

* `-i` · `--input <path>`
* `-o` · `--output <path>`
* `-f` · `--format <name>` (where applicable)
* `-q` · `--quiet`
* `--verbose`

## REST API

`screenjson serve` exposes the same engine over HTTP. See [API Reference → screenjson-cli server](/api-reference/cli/introduction).
