route planner on Use on own websites map?

Can I include the route planner (shown on in my own map? I am using leafletjs but its plugins don’t satisfy my needs.

If not, is it possible to offer a link to which opens the site with its route planners field pre-filled? Maybe through REST API?

Why don’t you try to include a solution directly from or or others listed on → ONLINE-ROUTING in your web site?
