|
|
|
+ summary: HTTP API for ingesting sensor readings and retrieving vending machine status.
|
|
|
+ description: |
|
|
|
+ Handwritten OpenAPI specification for the Getraenkeautomat Monitor application.
|
|
|
+
|
|
|
+ The API currently exposes two endpoints:
|
|
|
+ - `POST /api/v1/readings.php` for ingesting one sensor measurement
|
|
|
+ - `GET /api/v1/status.php` for retrieving the aggregated application state
|
|
|
+
|
|
|
+ The readings endpoint uses Bearer token authentication. The status endpoint is
|
|
|
+ intentionally public so the dashboard can poll it without a login.

|
|
|
+ Processing behavior:
|
|
|

|

|
+ - Updates `data/state.json` on success
|
|
|
+ - Triggers alerts only when the slot state changes from `ok` to `critical`
