How are characters counted and billed in document translations processed via the API?
For DeepL API Free:
With our limited API plan, you can translate up to 500,000 characters per month for free.
Please consider that a minimum of 50,000 characters will be counted for each document translated, even if the document contains fewer characters. This is done to cover the cost of processing the document. Documents containing more than 50,000 characters will be counted to the exact character.
For DeepL API Pro:
With a DeepL API Pro subscription, you are entitled to as many document translations as you like.
These, however, are billed singularly, following the usage-based pricing model: a fixed price of €4.99 per month + usage-based costs of €0.00002 per translated character.
Please consider that a minimum of 50,000 characters will be billed for each document translated, even if the document contains fewer characters. This is done to cover the cost of processing the document. Documents containing more than 50,000 characters will be billed to the exact character.
