Dota Gem Version Build Status Code Climate Test Coverage

dota is a Ruby client for the Dota 2 WebAPI.


Valve provides a GetSupportedAPIList endpoint that returns all the available endpoints in their API you can use, along with the parameters they accept. The following are supported by dota:

  • GetLeagueListing
  • GetMatchDetails
  • GetMatchHistory
  • GetFriendList
  • GetHeroes
  • GetGameItems
  • GetRarities
  • GetTeamInfoByTeamID
  • GetLiveLeagueGames
  • GetScheduledLeagueGames

Unsupported endpoints (including GetSupportedAPIList) can still be queried via custom requests using Dota.api.get.


Add this line to your application's Gemfile:

gem 'dota', '~> 0.0.21'

And then execute:

$ bundle

Or install it in your local repository:

$ gem install dota -v 0.0.21


Get your Steam API key here and make sure the gem is configured to use it. If you're using Rails, this might go in an initializer like config/initializers/dota.rb.

Dota.configure do |config|
  config.api_key = ENV.fetch("STEAM_API_KEY")

  # Set API version (defaults to "v1")
  # config.api_version = "v1"

Then use the client:

api = Dota.api

api.heroes(43)                   # => (Cached) A single hero - "Death Prophet"
api.heroes                       # => (Cached) All heroes

api.items(114)                   # => (Cached) A single item - "Heart of Tarrasque"
api.items                        # => (Cached) All items

api.abilities(5003)              # => (Cached) A single ability - "Mana Break"
api.abilities                    # => (Cached) All abilities

api.cosmetic_rarities            # => All cosmetic rarities

api.teams(1375614)               # => A single team - "Newbee"
api.teams                        # => A list of teams
api.teams(after: 1375614)        #    Allowed options:

                                 #    :limit - Integer, Amount of teams to return (default is 100)

api.leagues                      # => All leagues

api.matches(789645621)           # => A single match - "Newbee vs Vici Gaming"
api.matches                      # => A list of matches
api.matches(hero_id: 43)         #    Allowed options:
                                 #    :hero_id     - Integer, With this hero. See Dota::API::Hero.mapping
                                 #    :after       - Integer, With match IDs equal or less than this
                                 #    :player_id   - Integer, With this player (32-bit Steam ID)
                                 #    :league_id   - Integer, In this league. Use Dota.leagues to get a list of leagues
                                 #    :mode_id     - Integer, In this game mode. See Dota::API::Match::MODES
                                 #    :skill_level - Integer, In this skill level (ignored if :player_id is provided). See Dota::API::Match::SKILL_LEVELS
                                 #    :from        - Integer, Minimum timestamp
                                 #    :to          - Integer, Maximum timestamp
                                 #    :min_players - Integer, With at least this number of players
                                 #    :league_only - Boolean, Only league matches
                                 #    :limit       - Integer, Amount of matches to return (default is 100)

api.live_matches                 # => All live league matches
api.live_matches(league_id: 600) #    Allowed options:
                                 #    :league_id - Integer, In this league. Use Dota.leagues to get a list of leagues
                                 #    :match_id  - Integer, With this match

api.scheduled_matches            # => All scheduled league matches
api.scheduled_matches(from: 123) #    Allowed options:
                                 #    :from - Integer, Minimum timestamp
                                 #    :to   - Integer, Maximum timestamp

api.friends(76561198052976237)   # => All friends of user

Custom Requests

For the unsupported endpoints, you can use api.get. For example, the following code is similar to api.matches(789645621) except it will return the raw JSON payload instead of an array of Dota::Matches.

api.get("IDOTA2Match_570", "GetMatchDetails", match_id: 789645621)

Setting api_version here also overrides the current configuration:

api.get("IDOTA2Match_570", "GetMatchDetails", match_id: 789645621, api_version: "v1")

Caveat: Getting a list of matches via api.matches will call GetMatchHistory which has very few attributes for the matches returned (obviously for performance reasons), as opposed to getting info about a particular match via api.matches(id) which will instead call GetMatchDetails. In both cases, the matches returned will be instances of Dota::API::Match. In the future, there will be subclasses to distinguish the two.

When an instance method in a Dota::API::Match class returns nil, it most likely means the endpoint called doesn't provide it yet.
