Wheelchair objects api

Hello!
How to get objects with wheelchair properties from selected area? Response is too many objects… And not all have wheelchair property…

my request is:
http://api.openstreetmap.org/api/0.6/relations/search?type=wheelchair&value=yes&bbox=24.7292,48.9336,24.7620,48.946&bbox=24.73014,48.93811,24.74698,48.94459
What is wrong?

You should use Overpass for querying, the API is meant for editors.
You need something along the lines of: http://overpass-turbo.eu/s/j7N

BTW, do you know: https://wheelmap.org ?
