API:Geosearch

From mediawiki.org
Jump to navigation Jump to search

GET request to search for wiki pages near a location with geographic coordinates or page name.

This module is supported through the Extension:GeoData currently not installed on MediaWiki but Wikipedia. So, in this document, we will use the URL en.wikipedia.org in all API endpoints.

Example 3: Search for pages nearby with images[edit]

GET request[edit]

As an enhancement to Example 2, here we use the Generator module to get search results for pages near Wikimedia Foundation headquarters with images. Parameters passed along with a generator must be prefixed with a g. Note that in the query below, we've changed gscoord to ggscoord.

Demo app(s)[edit]

  • Special:Nearby on English Wikipedia shows articles of places around you
    Screenshot of Wikipedia iOS app - shows places around Wikimedia Foundation HQ
  • Wikipedia Mobile Apps use this API to show nearby locations. API usage can be seen in the source code of Android and iOS app
  • Nearby is an app for the Pebble smart watch that fetches Wikipedia articles near you.

Possible errors[edit]

Code Info
invalid-coord Invalid coordinate provided (Latitude and Longitude should be separated by pipe (|) symbol)

Additional notes[edit]

  • This module is supported through the Extension:GeoData, currently installed on Wikimedia Commons, all Wikipedias, all Wikivoyage sites, and some other wikis. You can use Special:Version of a wiki to check if the extension is listed there.
  • In addition to using the API as to ask for a page coordinates (as explained in Example 1), here are a few more ways to obtaining them:
    • If you want your user's current location, it's available through many OS-specific APIs. Recent browsers have an opt-in navigator.geolocation object. See MDN docs.
    • If you want the user to provide coordinates, there are various services that let the user pick from a map. See w:Wikipedia:Obtaining geographic coordinates.
