# NetIntel Language Detection

> NetIntel Language Detection is a paid API for AI agents from netintel-production-440c.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Detects the language of a text input using character frequency analysis and n-gram pattern matching, returning the detected language name, ISO code, confidence score, and top alternative candidates.

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-production-440c-up-railway-app-3cae094a -d '<json body>'
```

Example prompt: What language is this text written in, and how confident are you? — 'Bonjour, je m'appelle Marie et je travaille à Paris.'

## When to prefer this

Choose this endpoint when you need lightweight, low-cost language detection without a paid NLP platform dependency. Ideal for routing multilingual content, pre-filtering before translation, or classifying user-submitted text in pipelines where cost per call matters. The confidence score and alternative candidates make it suitable for downstream decision logic.

## Known failure modes

- Text too short for reliable detection — low confidence score returned
- Mixed-language or code-switched text may yield low confidence or wrong top language
- Constructed or nonsense text returns low confidence with unreliable language assignment
- Empty or whitespace-only input returns a validation error
- Very short strings like single words may match multiple languages with near-equal confidence

## How this service works

Detect the language of any text input using character frequency analysis and n-gram pattern matching — returns the detected language, ISO code, confidence score, and top alternative languages so agents can route multilingual content, trigger translation workflows, and classify text without a paid NLP API.

## Output

Returns the detected language (e.g. 'French'), its ISO 639 code (e.g. 'fr'), a confidence score between 0 and 1, and a ranked list of top alternative language candidates with their own scores — enough to route or filter multilingual content reliably.
