How this service works

Locus public pay-per-use API

Output

A JSON object containing an array of supported DeepL languages, each with a language code and name, filtered by type (source or target). Also includes payment metadata such as settled USDC amount and a request ID for tracking.

Example use cases

Populate translation language dropdown

“Get me all the target languages DeepL supports — I need to populate a dropdown in my app so users can pick what language to translate into.”

Check available source languages

“Fetch the list of source languages from DeepL so I can see which languages users can translate from.”

Validate a language code before translating

“Before I submit a translation job, can you pull the DeepL supported languages list and confirm that Polish is available as a target language?”

Endpoint

POSThttps://deepl.x402.paywithlocus.com/deepl/languages

When to prefer

Use this endpoint when you need to enumerate DeepL's supported languages programmatically — e.g. to build a language selector UI, validate a language code before submitting a translation, or discover what languages are available without hardcoding them. Prefer this over scraping DeepL's docs or maintaining a static list.

Side effects

Invalid 'type' value (not 'source' or 'target') may return an error or default to source languages
Payment failure if x402 USDC funds are insufficient
Network timeout from the Locus proxy layer
DeepL API downtime causing upstream failure
