Requirements

You need to have a valid [DeepL Pro Developer](www.deepl.com/pro#developer) account with an associated API key. This key must be made available to the application, e. g. via environment variable:

“`bash export DEEPL_API_KEY=YOUR_KEY “`

## Example

“`text require “deepl_api”

deepl = DeeplAPI::DeepL.new( api_key: ENV ) usage = deepl.usage_information()

> #<DeeplAPI::UsageInformation:0x00007fcbc588cc08 @character_limit=250000, @character_count=1450>¶ ↑

translation = deepl.translate( source_language: “DE”, target_language: “EN-US”, texts: [“ja”] )

> [{“detected_source_language”=>“DE”, “text”=>“yes”}]¶ ↑

“`
