  client.config.company      = "<api-company>"
  client.config.username     = "<api-username>"

Adding or deleting items

data = [
  {
    url: "http://url-to-image",
    filepath: "/path/to/image",
    metadata: {
      ...
    }
  },
  {
    url: "http://url-to-other-image",
    filepath: "/path/to/another/image",
    metadata: {
      ...
    }
  },
]

client.add(data) # add the image to the collection

client.delete(["/path/to/image", another_"/path/to/image"] ) # delete images
client.delete("/path/to/image") # pass a single filepath to delete a single image

searching the index

# searching for similar colors
params = {
  colors: [

search_options = Multicolor::REST::SearchBuilder.new(params).request

response = client.color_search(search_options)
response.body # returns API response
