I think I’ve just found a solution outside the place IDs! Using the “Bounding Box” on the Explore map, I created a bounding box to cover the entire world and got this chunk of url:
&nelat=69.53404715698059&nelng=180&place_id=any&swlat=-68.52872745050472&swlng=-180
There a few outliers with broken location, but the ones with maybe “null” location may be removed.
