# Retrieve a billable metric

> This endpoint retrieves an existing billable metric that represents a pricing component of your application. The billable metric is identified by its unique code.

<RequestExample>
  ```bash cURL
  LAGO_URL="https://api.getlago.com"
  API_KEY="__YOUR_API_KEY__"

  curl --location --request GET "$LAGO_URL/api/v1/billable_metrics/:code" \
  --header "Authorization: Bearer $API_KEY"
  ```

  ```python Python
  from lago_python_client.client import Client
  from lago_python_client.exceptions import LagoApiError

  client = Client(api_key='__YOUR_API_KEY__')

  try:
      client.billable_metrics.find('code')
  except LagoApiError as e:
      repair_broken_state(e)  # do something on error or raise your own exception
  ```

  ```ruby Ruby
  require 'lago-ruby-client'

  client = Lago::Api::Client.new({api_key: '__YOUR_API_KEY__'})

  client.billable_metrics.get('code')
  ```

  ```js Javascript
  await client.billableMetrics.findBillableMetric('code');
  ```

  ```go Go
  import "fmt"
  import "github.com/getlago/lago-go-client"

  func main() {
  lagoClient := lago.New().
      SetApiKey("__YOUR_API_KEY__")

  billableMetric, err := lagoClient.BillableMetric().Get("__BILLABLE_METRIC_CODE__")
  if err != nil {
      // Error is *lago.Error
      panic(err)
  }

  // billableMetric is *lago.BillableMetric
  fmt.Println(billableMetric)
  }
