## 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 tempest-ai-text-translation-946d755e -d '<json body>'
```

Example prompt: Can you translate the following paragraph into Spanish? The source is English: 'Our new product line launches next quarter and we're excited to share it with our customers.'

## When to prefer this

Choose this endpoint when you need AI-powered, pay-per-call language translation without a subscription, particularly in agentic or automated pipelines that pay with USDC via x402. It is well-suited for on-demand localization of short to medium text snippets such as product descriptions, UI strings, or customer messages, especially when source language auto-detection is useful.

## Known failure modes

- Missing required 'text' or 'target_language' fields returns a validation error
- Unsupported or misspelled language codes may result in a failure or fallback response
- Very long texts may exceed processing limits or increase latency
- Payment failure (insufficient USDC) blocks the request at the x402 layer
- Auto-detection may fail or misidentify the source language for very short or ambiguous inputs

## How this service works

Compose, rewrite, translate, and refine content at scale. 25 AI-powered endpoints. Pay-per-call with USDC on Tempo.

## Output

Returns a JSON object with a 'success' boolean and a 'data' object containing the translated text in the target language. If source_language is omitted, the API auto-detects it before translating.
