+#api/syscall
+
+The Sync API provides functions for interacting with the sync engine when the client runs in Sync mode.
+
+## Sync Operations
+
+### sync.isSyncing()
+Checks if a sync is currently in progress.
+
+Example:
+```lua
+if sync.isSyncing() then
+    print("Sync in progress...")
+end
+```
+
+### sync.hasInitialSyncCompleted()
+Checks if an initial sync has completed.
+
+Example:
+```lua
+if sync.hasInitialSyncCompleted() then
+    print("Initial sync completed")
+else
+    print("Waiting for initial sync...")
+end
+```
+
+### sync.performFileSync(path)
+Immediately synchronizes a file with the server. Returns once the synchronization has completed.
+
+Example:
+```lua
+sync.performFileSync("notes/important.md")
+```
+
+### sync.performSpaceSync()
+Immediately triggers a full space sync. Returns `-1` if a sync was already ongoing, or the number of sync operations performed.
+
+Example:
+```lua
+local changes = sync.scheduleSpaceSync()
+print("Number of changes synced: " .. changes)
+```
