How this service works
List all supported source and target languages with formality support info.
Output
An array of language objects, each containing the language name (e.g. 'Arabic'), its ISO language code (e.g. 'AR'), and a boolean flag indicating whether that language supports formality settings (formal/informal tone).
Example use cases
Example prompt
“Can you give me the full list of languages DeepL supports as translation targets, including which ones support formality options?”
Technical details
Endpoint
POSThttps://deepl.mpp.paywithlocus.com/deepl/languages?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to dynamically discover which languages DeepL supports before constructing a translation request, validate a user-provided language code, populate a language picker UI, or determine whether a specific language supports formality. Prefer this over hardcoding language lists to stay in sync with DeepL's current capabilities.
Side effects
- Invalid 'type' value (not 'source' or 'target') may return an error or default to source languages
- Empty or malformed request body defaults to source language list
- Network or upstream DeepL API errors may result in 5xx responses
