Request Parameters

  • key required

    The API Key, which is needed to make requests to MapQuest services.

  • location required

    The location to geocode.

    Example: Single Line Location

    location=Denver,CO

  • boundingBox optional

    When ambiguous results are returned, any results within the provided bounding box will be moved to the top of the results list. Bounding box format is: upper left latitude, upper left longitude, lower right latitude, lower right longitude.

    Example: Bounding Box

    boundingBox=40.099998,-77.305603,39.099998,-75.305603

  • ignoreLatLngInput optional, defaults to false

    This option tells the service whether it should fail when given a latitude/longitude pair in an address or batch geocode call, or if it should ignore that and try and geocode what it can.

    • true: The geocoder will ignore the LatLng specified in the location, and use the address info to perform geocode
    • false : The geocoder will return a geoaddress object containing the LatLng passed in and write a warning message to Info block
    Example: Ignore Lat Lng Input

    ignoreLatLngInput=true

  • thumbMaps optional, defaults to true

    This parameter tells the service whether it should return a URL to a static map thumbnail image for a location being geocoded.

    • true: The response will include a URL to a static map image of the geocoded location.
    • false : The response will not include a static map image URL.
    Example: Disable Static Map Response

    thumbMaps=false

  • maxResults optional

    The max number of locations to return from the geocode

    This option will only have an effect on the second location because it is ambiguous

    Example: Five Results Max

    maxResults=5

  • outFormat optional, defaults to json

    Specifies the format of the response. Must be one of the following, if supplied:

    • json
    • xml
    • csv (character delimited)
    Example: XML response

    outFormat=xml

  • delimiter optional, defaults to none, only in effect if outFormat=csv

    Specifies the delimiter used in the csv response

    • ,
    • |
    • :
    • ;
    Example: Pipe Delimiter

    delimiter=|

  • intlMode optional, defaults to auto

    Allows users of the International Geocoder to tell MapQuest how to handle a 5-box geocode.

    • 5BOX: Keeps the query as a 5-box and sends it to the TomTom International Geocoder as a 5-box.
    • 1BOX: Converts the 5-box query into a 1-box query and sends it to the TomTom International Geocoder.
    • AUTO: Handles the query in a way deemed most optimal by MapQuest. Currently, this converts a 5-box query to a 1-box query across the board.
    Example: 1BOX International Mode

    intlMode=1BOX

  • callback optional

    A JavaScript function name. The JSON-formatted response will be wrapped in a call to the supplied callback function name to provide JSONP functionality. This functionality might be needed to do cross-site scripting. See the Wikipedia.org entry for JSON for more details.

    Example: Callback

    callback=geocodeResult
