# Inference402 Machine Translation

> Inference402 Machine Translation is a paid API for AI agents from inference402.worlddata402.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-19).

Translates text between languages using Meta's M2M100 model, with support for Egyptian Arabic and other languages, paid per-call via USDC on Base.

## 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 inference402-machine-translation-e58d8596
```

Example prompt: Translate this text from English to French using the Inference402 pay-per-call translator: 'The meeting has been moved to Thursday morning.'

## When to prefer this

Choose this endpoint when you need pay-as-you-go machine translation with no API key or account setup, particularly for agents that require occasional translation calls billed in USDC on Base. Well-suited for Egyptian Arabic and other languages supported by M2M100. Prefer this over subscription-based translation APIs when cost predictability at the per-call level is important, or when operating in a crypto-native payment context via x402.

## Known failure modes

- Unsupported language pair returns an error or empty translation
- Text exceeding 5000 characters is rejected
- Missing or invalid ISO 639-1 language code causes a bad request
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- Low-resource languages may produce lower-quality translations

## How this service works

Pay-per-call AI inference for agents: chat (Llama 3.3 70B / 3.1 8B), structured JSON, summarize, translate (incl. Egyptian Arabic), extract, classify, sentiment, keywords, rewrite, embeddings, moderation, vision and speech-to-text. USDC on Base mainnet over x402. No API key, no account.

## Output

Returns a JSON object containing the translated text string, the source language code used, the target language code, and the model identifier (e.g. @cf/meta/m2m100-1.2b). Example: {model: '@cf/meta/m2m100-1.2b', source: 'en', target: 'fr', translated_text: 'La réunion est déplacée à jeudi matin.'}
