`spaceapid` serves a [SpaceAPI](https://spaceapi.io)-compatible JSON on port 8080:

See [Running](#Running) for details.
## Updating values
The state of the boolean `state->open` property can be modified via `/state/open`:
```shell
curl -X PUT -u user:password -d true http://[::1]:8080/state/open
```
The same is true for the endpoints for sensors configured under `"dynamic"`.
Currently only the sensors with the `value/unit/location/name/description` schema are implemented.
At the time of writing this includes `temperature`, `barometer`, `humidity`, `beverage_supply`, `power_consumption`, and `account_balance`.
Out-of-spec sensors may be used as well, as long as they share the same schema.
```shell
curl -X PUT -u user:password -d 23.42 http://[::1]:8080/sensors/{temperature,humidity,...}[/location[/name]]
```
As can be seen in the example, the http urls are generated from sensor type and optionally `location` and `name`.
Depending on sensor type, `location` might be required for your sensors, see the schema for details.
## Building
See the `go.mod` file for minimum required Go version.

## Updating values
The state of the boolean `state->open` and `state->message` property can be modified via `/state/{open,message}`:
```shell
curl -X PUT -u user:password -d true http://localhost:8080/state/open
curl -X PUT -u user:password -d "Nur mit Passierschein A38 :3" http://localhost:8080/state/message
```
As `state->message` is optional, its value can be deleted by using the `PUT` method with an empty payload, or by using `DELETE`:
```shell
curl -X PUT -u user:password -d "" http://localhost:8080/state/message
# OR
curl -X DELETE -u user:password http://localhost:8080/state/message
```
The same updating procedure applies for the endpoints for sensors configured under `"dynamic"`.
