# Geo Wikipedia API
> Wikipedia, located — find the Wikipedia articles near any coordinate ("Wikipedia near me") as an API, live from the official MediaWiki API. Pass a latitude and longitude and get the nearby places, landmarks and points of interest with their distance in metres, a two-sentence summary, a thumbnail image and a link — perfect for travel guides, maps, augmented-reality and location-aware apps. Or look up a single article to get its coordinates, description, summary and image. Works for every language edition (en.wikipedia, de.wikipedia, fr.wikipedia and 300+ more). Open data from Wikipedia.
