How to extract intersections in the OpenStreetMap？ I need the longitude and latitude of the intersections, thanks!

There has been a similar question here. There is no direct API call to retrieve intersections. But you can query all ways in a given bounding box (for example directly via the API or via the Overpass API) and look for nodes shared by two or more ways as explained in the other answer.
