+# API
+
+There is a web API for getting information about things that are bridged with Out Of Your Element.
+
+The base URL is the URL of the particular OOYE instance, for example, https://bridge.cadence.moe.
+
+No authentication is required.
+
+I'm happy to add more endpoints, just ask for them.
+
+## Endpoint: GET /api/message
+
+|Query parameter|Type|Description|
+|---------------|----|-----------|
+|`message_id`|regexp `/^[0-9]+$/`|Discord message ID to look up information for|
