Search and routes
The search, routing, and panorama features are not available on the Constructor map by default.
To use these features, you need to get an API key in Developer Dashboard for the «JavaScript API» product and add it to the code.
Sample code using the API key:
<script type="text/javascript" charset="utf-8" async src="https://api-maps.yandex.ru/services/constructor/1.0/js/?um=constructor:%3A053bd947d462cc1a45aeba4070defff75501905071c0eaf68436ac9976ec698c&width=602&height=400&lang=ru_RU&scroll=true&apikey=<your API key>">
</script>
