## 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 momoai-translation-api-c2b72b94 -d '<json body>'
```

Example prompt: Translate this product description into Japanese with a formal tone: 'Our new wireless headphones deliver crystal-clear audio and 30-hour battery life.'

## When to prefer this

Choose this endpoint when you need LLM-quality translation with tone control, auto language detection, and pay-per-call billing in USDC — especially suited for agents that need ad-hoc translation without subscription commitments. Prefer over batch translation services when per-call micropayment pricing is acceptable and translation quality from a conversational LLM is desired.

## Known failure modes

- Missing required fields (text or target_lang) returns a validation error
- Unsupported language code returns an error or poor-quality translation
- Insufficient USDC balance causes payment failure and no translation is returned
- Very long text may exceed model context limits and return an error
- Ambiguous or low-resource language codes may produce inaccurate translations

## How this service works

Pay-per-use LLM API. Chat, reasoning, code review, translation, summarization, data extraction, and more. Pay with USDC on Base.

## Output

Returns a JSON object with a success flag and a data object containing the translated text, detected or specified source language, target language, tone used, the underlying model name, and token usage stats.
