## 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 api-strale-io-da9dfef1
```

Example prompt: Translate the following text to French: 'The quick brown fox jumps over the lazy dog' — auto-detect the source language.

## When to prefer this

Use this endpoint when you need to translate arbitrary text between any major world languages with auto-detection of the source language, and want a confidence score alongside the translated result. Ideal for agents that process multilingual user input or need to localize content on the fly without specifying the source language explicitly.

## Known failure modes

- Missing required 'text' parameter returns 400 error
- Missing required 'target_language' parameter returns 400 error
- Unsupported or unrecognized target language returns error
- Very short or ambiguous text may result in low confidence score
- Payment of 0.054001 USDC required per call; missing payment returns 402 error
- Extremely long text inputs may be rejected or truncated

## How this service works

Translate text between languages. Auto-detects source language. Supports all major languages. Returns translated text with confidence.

## Output

Returns the translated text in the target language along with a confidence score for the translation, and the detected source language if auto-detection was used.
