47**Content-Type Support**:
48- `application/json` - Standard fetch requests
49- `text/plain` - sendBeacon requests (automatically parsed as JSON)

197// 500 - Server Error
198{
199 error: "Failed to fetch page data",
200 details: "Notion API error message"
201}
18 - Triggers when user closes tab, navigates away, or browser crashes
19 - Uses `navigator.sendBeacon()` for maximum reliability during page unload
20 - Falls back to synchronous `fetch` if `sendBeacon` fails
21 - **Most reliable** for normal user behavior
22
24 - Triggers when user navigates within the app (SPA navigation)
25 - Runs when React component unmounts normally
26 - Uses standard `fetch` with full error handling
27 - **Reliable** for in-app navigation

20### `useGlimpseData.ts`
21Manages glimpse data fetching and state.
22
23**Parameters:**
24- `glimpseId` - ID of the glimpse to fetch
25- `initialData` - Optional initial data to avoid refetching
26
27**Returns:** `UseGlimpseDataReturn`
29- `loading` - Loading state
30- `error` - Error state
31- `refetch` - Function to manually refetch data
32
33**Usage:**
34```typescript
35const { data, loading, error, refetch } = useGlimpseData(glimpseId, initialData);
36```
37
38### `useAgentData.ts`
39Manages agent data fetching with automatic polling.
40
41**Parameters:**
68**Session Tracking:**
69- Uses `sendBeacon` API for reliable session ending during page unload
70- Falls back to synchronous fetch if sendBeacon fails
71- Handles both normal component unmount and browser tab closure
