Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 devx-voice-machine-translation-6fa22c09 -d '<json body>'
```

Example prompt: Translate this text into German for me: 'Good morning, how are you today?' — auto-detect the source language.

## When to prefer this

Choose this endpoint when you need pay-per-use machine translation across up to 100 languages with no subscription, billed only for successful translations at $0.001 USDC per 1,000 characters. It is ideal for AI agents that need on-demand, cost-accountable translation with auto language detection, idempotency support, and compatibility with both DevX-native and LibreTranslate-style ({q, source, target}) request formats.

## Known failure modes

- Text exceeds 5,000 character limit — request rejected without charge
- Invalid or unsupported target_lang enum value — validation error returned
- Source text is empty or missing — request rejected
- Network or model inference failure — not charged, error response returned
- Invalid idempotency key format — request rejected with schema validation error

## How this service works

Machine translation for agents between 100 languages: send text (up to 5,000 chars), target_lang and optional source_lang (auto-detect by default) and get the translation. $0.001 USDC per started 1,000 characters on Base; failures are not charged. LibreTranslate/dTelecom-style {q, source, target} also accepted at /v1/translation. M2M100 1.2B. By DevX.

## Output

Returns a JSON object containing the translated text, the source and target language codes, character count, number of billed units, the model used (m2m100-1.2b), an operation ID, and payment confirmation details including transaction hash and amount paid in USDC.
