## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability deepl-languages-list-via-locus-x402-8a0420d4 -d '<json body>'
```

Example prompt: Can you fetch the full list of target languages that DeepL supports so I can show them in my translation app's language picker?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works
