Markers API

Markers API

The Markers API searches for organizations, buildings, and places to display markers on the map. A marker is a representation of an object on the map, so the marker can only be an object with coordinates.

You can search by:

  • company name (“Moos Hair Dressing”)
  • company's business area (“restaurants” or “music instrument stores”)
  • with geotags (“Al Mankhool flowers”)
  • attributes of goods and services (“Italian cuisine café” or “Sauna with a pool”)
  • telephone number or website (“97143017777” or “www.marinaviewhotel.com”)
  • without specifying a text query (in a building, in a category, in a city, search for all branches of one company)
  • makani (“12991 75289”)

Requests are made using the GET method, all required parameters should be passed in the query string. The response is returned in the JSON format.


Here is an example of a request:

https://catalog.api.2gis.com/3.0/markers?q=cafe&location=37.630866,55.752256&key=YOUR_KEY

Request takes the following parameters:

  • q=cafe — the search is performed for the “cafe” query
  • location=37.630866,55.752256 — coordinates for a nearby cafe search
  • key=YOUR_KEY — your API key

The type parameter is used to filter objects by type in the query. The search will be performed only among objects of the type specified in the query. Filtering is possible for these most frequently used types:

  • by location — for example, in a certain district, city, in a given area
  • by the type of response data — e.g., only companies or only buildings
  • by category — e.g., a search for cafes or grocery stores only
  • by organization — you can get the list of all branches of an organization
  • by working hours — e.g., only branches working around the clock
  • by availability or absence of data, e.g., photos, reviews, rating, website, tax identification number
  • by additional attributes — e.g., the availability of Wi-Fi, the ability to pay by card, etc

The complete list of filters and their corresponding parameters can be found in the API reference.

You can enable sorting of the search result using the sort parameter in your query.

The search result is sorted by distance from the user's location, object rating and other parameters. Sorting types are defined in the API reference.

You can search for objects in a specific area on a map. This type of search allows you to get relevant results. Search options for an area on the map are:

  • geographical criteria in the text request — for example, "Moscow cafe"
  • the point from which the search is performed
  • search in a radius
  • search in a rectangular area
  • search in an arbitrary area
  • search in the city

To search for objects in an area on the map, the query should contain coordinates of the points within which the objects are to be found or an identifier of the city in which you want to search for objects. You can find more detailed description of the fields in the API reference, examples of the use of geographic search restrictions can be found in the corresponding section.

The request response is given in the JSON format:

{
    "meta": {
        "api_version": "3.0.448950",
        "code": 200,
        "issue_date": "20200626"
    },
    "result": {
        "items": [
            {
                "id": "70000001041443567",
                "type": "branch",
                "lat": 55.433435,
                "lon": 37.728608,
                "is_advertising": false
            }
        ],
        "total": 5926
    }
}

Parameters that are passed in the response by default:

  • id — object identifier
  • type — object type. Object types are defined in the API reference
  • lat — latitude;
  • lon — longitude;
  • is_advertising — A flag that indicates whether the advertiser.

The full list of additional information is defined in the API reference.

The search_type parameter is used to form the search result. The most commonly used algorithms for a search result generation are described below, the full list of algorithms can be found in the API reference.

In search results categories and organizations will be expanded to companies (branches of an organization). For example, a search for "Russian Post" will put all post offices in the search results. Category expansion works in a similar way — when searching for a "cafe", the result will contain companies from the "Cafe / Cafeteria" category rather than the category itself, which is also the subject of the catalog. This algorithm of result formation is used by default and matches the search_type=discovery parameter passed to the query.

It is similar to a search with expansion, but also keeps only one branch for each organization. For example, the user wants to find an online store and to look at its site, and he does not need all the pick-up points in the result. To use this algorithm of forming the search result you need to pass search_type=one_branch to the query.

It is suitable for searching organizations in a building, for example, in a business center or a mall. You can also use it to autocomplete when searching in the building. To use this algorithm of forming the search result, you need to pass search_type=indoor to the query and specify the building id in the building_id parameter.
