## 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 clink-lithium-vault-text-translation-api-91506673 -d '<json body>'
```

Example prompt: Can you translate this customer message into Japanese: 'Thank you for your order, it will arrive in 3-5 business days. Please contact us if you have any questions.'

## When to prefer this

Choose this endpoint when you need a no-account, pay-per-call translation API that returns clean machine-readable JSON (source language + translation) for up to 5,000 characters. Ideal for AI agents that need to handle multilingual text without managing API keys or subscriptions. At $0.01 per call it suits sporadic, automated, or bursty translation workloads where a subscription service would be overkill.

## Known failure modes

- Text exceeds 5,000 character limit — request rejected
- Unsupported or unrecognized target language string — may return error or fallback
- Payment of $0.01 USDC not completed — 402 Payment Required response
- Empty text field — likely returns error or empty translation
- Extremely rare or low-resource language pairs may produce low-quality translations

## How this service works

Translate text for AI agents - POST any text up to 5,000 chars with a target language, get clean JSON back: the detected source language + the full translation, never prose. Any language pair - Spanish, French, German, Japanese, Chinese, Korean, Arabic, Hindi, Portuguese, English - source auto-detected when omitted. Translation API, language translation, localize, i18n. No API key, no account. POST {text, target_lang, source_lang?}. Free sample: /translate/example.

## Output

Returns a JSON object containing the detected source language code (e.g. 'en', 'de') and the full translated text in the requested target language. No prose or filler — just clean structured output.
