# Cloud phone screen capture(response base64)

Capture the Cloud Phone screen and return the image inline as base64.
- **Preconditions**: the phone must be powered on and not held by another member. **Supported on compatible device models only** — incompatible models reject the call.
- **Completion**: synchronous. On failure the response carries an error message instead of image data, so check `success` before decoding.
- **Model support**: documented as available on Android 12 and Android 15 images only.
- **Use**: prefer this over `/cloudphone/screenCap` when you do not want to depend on a temporary download URL.
