+## `POST /action/verify`
+
+Execute one action and wait for a structured success condition.
+
+Query params:
+

+
+```json
+{
+  "action": {
+    "action": "click",
+    "target": {"mode": "pixel", "x": 1300, "y": 740}
+  },
+  "condition": {
+    "kind": "text",
+    "mode": "screen",
+    "text": "Settings",
+    "match": "contains",
+    "present": true,
+    "language_hint": "eng",
+    "min_confidence": 0.4

+  "retries": 1,
+  "timeout_ms": 4000,
+  "poll_interval_ms": 250,
+  "retry_delay_ms": 250
+}
+```

+Condition kinds mirror `POST /wait`:
+- `text`
+- `window`
+- `visual`
+
+The response returns per-attempt action output plus structured verification output.
