# netintel.dev Translate Long

> netintel.dev Translate Long is a paid API for AI agents from netintel.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Translates long-form text from one language to another, returning a graded translation with quality scoring and source language detection

## Facts

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 netintel-dev-translate-long-e28011cd -d '<json body>'
```

Example prompt: Translate this 300-word English article about the James Webb Space Telescope into German and give me a quality grade on the translation: 'The James Webb Space Telescope has captured its deepest infrared image of the universe yet, revealing thousands of galaxies in a tiny patch of sky.'

## When to prefer this

Choose this endpoint when you need to translate substantial, long-form content (paragraphs or full documents) and also want a quality grade and score alongside the translated output. Prefer this over short-text translation endpoints when the content exceeds a sentence or two in length. The grading feature makes it especially useful when translation quality assurance matters, such as for publishing or professional use.

## Known failure modes

- Unsupported language pair returns an error or low service_score
- Text too short for 'long' tier may be rejected or scored poorly
- Missing or malformed target_language parameter causes a 4xx error
- Micropayment failure via x402 results in 402 Payment Required with no translation returned
- Empty or null input text returns an error response

## How this service works

Translate up to 2000 words between languages using Claude Haiku — auto-detects source, supports 30+ target languages, preserves formatting, for larger documents and articles. For short snippets use the cheaper /translate/short.

## Output

A JSON object containing the translated text, detected source language, specified target language, a letter grade (e.g. 'A') for translation quality, a numeric service score out of 100, word count of the translation, a tier label ('long'), and an array of findings or issues identified during translation.
