As a DeepL API Pro user, you have the option to set a limit on the amount of characters, STT minutes, or STS minutes consumed across your entire subscription per month, limiting your maximum costs. You activate “Cost Control” on the “API Usage” tab, the central hub for usage and cost settings. This limit applies subscription-wide; for a limit on a single key instead, see Set a key-level usage limit.

​
Set a cost control limit

  1. Navigate to the “API Usage” tab
  2. Click to change cost control settings for the relevant unit — a separate link manages the limit for each of characters, STT minutes, and STS minutes
  3. Check the box to activate the limit
  4. Enter the maximum consumption per month
  5. Click “Submit” to save the changes
Your new cost control limit is applied immediately.

Per-unit links for managing subscription-level cost control

Once you reach your limit, DeepL stops processing further translation requests until the end of the usage period, to avoid exceeding your set maximum cost. If you want to translate more, you can change the cost control limit at any time. Within the characters unit, the limit is enforced against the sum of Translate API and Write API characters; it’s not possible to set separate limits for each. Characters, STT minutes, and STS minutes each have their own independent limit.

FAQ

​
I have been notified that my Cost Control was raised, but I didn’t raise it. What should I do?

Every time your “Cost Control” limit is raised, you receive a notification email for security reasons. If you receive such a notification but did not raise your “Cost Control” limit, we highly suggest you reset your authentication key and the password to your DeepL Pro account as soon as possible.
