Endpoints

Tiles

• /v1/tiles: Returns all the tiles in the map, with the legacy format:

{
  type: number
  x: number
  y: number
  owner?: string
  estate_id?: string
  name?: string
  top?: number
  left?: number
  topLeft?: number
  price?: number
}

This endpoint has been deprecated, you should use the /v2/tiles endpoint, more info below.

• /v2/tiles: Returns all the tiles in the map, with the following format:

{
  id: string
  x: number
  y: number
  type: 'owned' | 'unowned' | 'plaza' | 'road' | 'district'
  top: boolean
  left: boolean
  topLeft: boolean
  updatedAt: number
  name?: string
  owner?: string
  estateId?: string
  tokenId?: string
  price?: number
}

Filter: You can filter the results and the payloads using the following query params:

• x1,y1,x2,y2: You can request just a piece of the map, for example this will only return tiles between 10,10 and 20,20:

/v2/tiles?x1=10&y1=10&x2=20&y2=20

• include: You can select which fields to include in each tile, for example this would include only type, top, left and topLeft:

/v2/tiles?include=type,top,left,topLeft

• exclude: The opposite to the filter above, the fields you pass in this filter will be excluded from each tile, for example if you don't cate about the updatedAt and tokenId fields you can do:

/v2/tiles?exclude=updatedAt,tokenId

Map

• /v1/map.png: This endpoint returns a PNG of the genesis map. You can customize the following via query params:

  • width: The width in pixels of the image, ie: ?width=1024

  • height: The height in pixels of the image, ie: ?height=1024

  • size: The size in pixels of each tile, for instance if size is 10, all the tiles will be 10x10px, ie: ?size=10

  • center: The coords on which to center the map, ie: ?center=20,20

  • selected: A list of coords to be highlighted, separated with semicolons, ie: ?selected=10,10;10,11;11,10;11,11

  • on-sale: If true, the parcels and estates on sale will be displayed in blue.

Example:

/v1/map.png?center=23,-23&selected=23,-23&size=20&width=2048&height=2048

• /v1/parcels/:x/:y/map.png: This endpoint returns a PNG of the map already centered and highlighting a Parcel. You can also adjust width, height and size via query params

• /v1/estates/:id/map.png: This endpoint returns a PNG of the map already centered and highlighting an Estate. You can also adjust width, height and size via query params

• /v2/parcels/:x/:y: This endpoint returns metadata about a parcel by passing its coordinates. The metadata uses the OpenSea Metadata Standard.

• /v2/estates/:id: This endpoint returns metadata about an estate by passing its id. The metadata uses the OpenSea Metadata Standard.

• /v2/contracts/:address/tokens/:id: This endpoint returns metadata about a parcel or an estate, by passing the contract address and the token id. The contract address for LAND on mainnet is 0xf87e31492faf9a91b02ee0deaad50d51d56d5d4d and the contract address for Estate on mainnet is 0x959e104e1a4db6317fa58f8295f586e1a978c297.

• /v2/addresses/:address/contributions: Returns a list of contributions made by specific address. Each contribution includes the amount of parcels and the district id they were contributed to.

Troubleshooting

• Installing node-canvas on Apple M1:

If the npm install fails on the dependency node-canvas and you are running on an Apple M1 chip, try installing these dependencies via brew: brew install pkg-config cairo pango libpng jpeg giflib librsvg.
