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

Go to openstreetmap.org and zoom to the extent of your area of interest using the search box or the mouse. Click on Export Data in the sidebar on the left to bring up the Export pane. If you are satisfied with the visible extent, click Export. You will be prompted to save map.
The "query features" tool on the OpenStreetMap front page lets users click on the map and open the tags for elements near where they clicked. Query feature output. Note button in green color located on the right that was used to trigger this listing.
I would like to use OpenStreetMap maps. How should I credit you? You must also make it clear that the data is available under the Open Database Licence. This can be achieved by providing a "License" or "Terms" link which links to www.openstreetmap.org/copyright or www.opendatacommons.org/licenses/odbl.
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.
