# Text Translation API (28 Languages, Auto-Detect)

## 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 text-translation-api-28-languages-auto-detect-a0ff7c89
```

Example prompt: Can you translate this customer message into German: 'Thank you for your purchase, your order will arrive within 3 business days.'

## When to prefer this

Choose this endpoint when you need fast, inexpensive ($0.005/call) text translation into one of 28 common languages with automatic source detection, especially in agent workflows where you don't know the source language in advance. Ideal for short-to-medium text (under 3,000 chars). Prefer alternatives for very large documents, specialized domains (legal/medical), or languages outside the supported 28.

## Known failure modes

- Text exceeds 3,000 character limit — request rejected or truncated
- Unsupported target language code provided — returns error
- Malformed query parameters — missing required 'text' or 'to' fields
- Workers AI model timeout or rate limit — 5xx response
- Payment not processed (x402 protocol) — 402 response blocking the call

## How this service works

Invoice-to-JSON, on-chain tools (transaction explainer + payment check, wallet profile, contract ABI, ERC-20 token risk), company contacts and web-to-RAG for AI agents. Pay per call with x402 (USDC on Base). No signup, no API key.

## Output

A JSON object containing the translated text string, the detected or specified source language code, and the target language code (e.g. {"to": "de", "from": "auto", "translation": "Danke für das Gespräch heute..."}).
