## 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 quickbuild-translate-api-43e67815
```

Example prompt: Translate the following Markdown text into French, auto-detecting the source language, and keep it under 3000 characters: '# Bonjour le monde\nCeci est un exemple de texte en français.'

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call text or webpage translation powered by an LLM with auto language detection, support for Markdown, and a simple GET interface — especially when you want to translate a live public URL's content without pre-fetching it yourself.

## Known failure modes

- Missing or invalid URL when no text is provided may return a fallback Spanish sample translation
- Source character count exceeding maxChars results in truncation (truncated: true)
- Unsupported or unrecognized language codes may cause incorrect detection or mistranslation
- Unreachable or paywalled URLs will fail to extract content
- Very long texts beyond 20000 characters are rejected by schema validation

## How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

## Output

Returns a JSON object with the translated text, detected source language code, target language code, the AI model used, character counts for source and output, number of segments processed, whether the input was truncated, the page title (if a URL was provided), and the source type ('text' or 'url').
