JavaScript interface for the Gatherer card database

Build Status

Gatherer is the canonical source for Magic: The Gathering card details. While useful, it lacks an interface for retrieving this data programmatically. The lack of an API makes creating Magic-related applications unnecessarily difficult.

Tutor is a simple JavaScript interface for Gatherer.



tutor.card(id, callback(err, card))
tutor.card(name, callback(err, card))
tutor.card(details, callback(err, card))

The first and second forms are shorthand for tutor.card({id: id}, ...) and tutor.card({name: name}, ...) respectively. The callback is passed an object representing the specified card. Version-specific metadata such as flavor text and rarity are included for cards specified by id. Attributes not applicable to the card type (e.g. lands have no mana cost) or not present (e.g. certain creatures have no rules text) are omitted.

tutor.card 'Demonic Tutor', (err, card) ->
  # => "Demonic Tutor"
  console.log card.mana_cost
  # => "{1}{B}"
  console.log card.text
  # => "Search your library for a card and put that card into your hand. Then shuffle your library."

Split cards

Because the two sides of a split card share a Gatherer id, it's necessary to provide the name of the desired side:

tutor.card id: 27165, name: 'Fire', (err, card) ->
  # => "Fire"

tutor.card id: 27165, name: 'Ice', (err, card) ->
  # => "Ice"

Retrieving either side of a split card by name is straightforward:

tutor.card 'Fire', (err, card) ->
  # => "Fire"

tutor.card 'Ice', (err, card) ->
  # => "Ice"

Flip cards

Retrieving the top half of a flip card by id is straightforward:

tutor.card 247175, (err, card) ->
  # => "Nezumi Graverobber"

Either half of a flip card can be retrieved explicitly by setting which to "a" (for the upper half) or "b" (for the lower half):

tutor.card id: 247175, which: 'b', (err, card) ->
  # => "Nighteyes the Desecrator"

When retrieving a flip card by name rather than id, one may simply provide the name of the desired half:

tutor.card 'Nighteyes the Desecrator', (err, card) ->
  # => "Nighteyes the Desecrator"

Double-faced cards

Either face of a double-faced card can be retrieved by id:

tutor.card 262675, (err, card) ->
  # => "Afflicted Deserter"

tutor.card 262698, (err, card) ->
  # => "Werewolf Ransacker"

Or by name:

tutor.card 'Afflicted Deserter', (err, card) ->
  # => "Afflicted Deserter"

tutor.card 'Werewolf Ransacker', (err, card) ->
  # => "Werewolf Ransacker"


tutor.set(name, callback(err, set))

Scrape cards from the set specified by name. For example:

tutor.set 'Homelands', (err, cards) ->
  console.log cards.length
  # => 115
  console.log Object.keys(cards[0]).sort()
  # => [
  #   "converted_mana_cost",
  #   "expansion",
  #   "gatherer_url",
  #   "image_url",
  #   "mana_cost",
  #   "name",
  #   "power",
  #   "rarity",
  #   "subtypes",
  #   "supertypes",
  #   "text",
  #   "toughness",
  #   "types",
  #   "versions"
  # ]


tutor.formats(callback(err, formatNames))

Provides the names of all the game's formats:

tutor.formats (err, formatNames) ->
  console.log formatNames
  # => [
  #   "Classic",
  #   "Commander",
  #   ...
  #   "Vintage",
  #   "Zendikar Block"
  # ]


tutor.sets(callback(err, setNames))

Provides the names of all the game's sets:

tutor.sets (err, setNames) ->
  console.log setNames
  # => [
  #   "Alara Reborn",
  #   "Alliances",
  #   ...
  #   "Worldwake",
  #   "Zendikar"
  # ]


tutor.types(callback(err, types))

Provides the names of all the game's types:

tutor.types (err, types) ->
  console.log types
  # => [
  #   "Artifact",
  #   "Basic",
  #   ...
  #   "Vanguard",
  #   "World"
  # ]


npm install tutor --global will make the tutor command available globally.
