UK electric car charging points

The openchargemap provides an API and an iframe which can be embedded to display a map with the nearest electric car charging points. The result looks quite decent as an iframe although it doesn’t appear to pick up your coordinates and you have to enter a search post-code. Hoping someone can suggest how to pass the HASS lat-long or postcode?

    panel_iframe:
      pantilt:
        title: 'Electric charging points'
        url: 'https://map.openchargemap.io/?mode=embedded'

From the API it should be possible to create a sensor component to detect the nearest charging station. I would like this in order to be notified when a close charge point is added. Couldnt figure out the correct API request to get the nearest charge point however, if anyone else does please let me know.
Cheers

OK figured out how to query the API with a rest sensor. This sensor displays the distance (kM) to the nearest charging point as the crow flies. There is a lot more info returned by the API if anyone is interested in other details about the nearest charging points.
