+
+Query parameters

+{
+  "q": "string",
+  "providers": ["yt", "dm", "tw", "pt", "od", "ru"],
+  "groups": {
+    "yt": [
+      { "id": "string", "title": "string", "thumbnail": "string", "uploaderName": "string", "url": "string", "type": "video" }
+    ],
+    "dm": [],
+    "tw": [],
+    "pt": [],
+    "od": [],
+    "ru": []
+  },
+  "page": 1,
+  "pageSize": 24
+}
+```
+
+Error responses
+- 400 { error: "invalid_query", details: "min_length_2" }
+- 500 { error: "search_failed", details: "..." }
+
+Providers
+- yt: YouTube
+- dm: Dailymotion
+- tw: Twitch
+- pt: PeerTube
+- od: Odysee
+- ru: Rumble
+
+Notes
+- Each provider is queried in parallel with a per-provider limit equal to `pageSize`.
+- The endpoint currently does not expose a `total` field; the frontend should offer a simple Next page affordance or infinite scroll when appropriate.
+- Future: support for `sort`.
