Request Parameters

Request ParameterDescriptionRequired
keyThe API Key, which is needed to make requests to MapQuest services.Yes
outFormatSpecifies the format of the response. Must be one of the following, if supplied:
  • json
  • xml
  • csv (character delimited)

Example: Callback

Request Body

Request ParameterDescriptionRequired
locationThe location to geocode.

Example: Single Line Location
"location": "Washington,DC"

Options Object

Request ParameterDescriptionRequired
boundingBoxWhen 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": {"ul": { "lng": -77.085411, "lat": 38.893276 }, "lr": { "lng": -77.071159, "lat": 38.848869 }}
ignoreLatLngInputThis 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
optional, defaults to false
thumbMapsThis 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
optional, defaults to true
maxResultsThe 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
delimiterSpecifies the delimiter used in the csv response
  • ,
  • |
  • ;
Example: Pipe Delimiter
"delimiter": "|"

optional, defaults to none, only in effect if outFormat=csv
intlModeAllows 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"
optional, defaults to auto
