## 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 nexusapi-text-language-detection-01f82e3f -d '<json body>'
```

Example prompt: What language is this text written in: 'Bonjour, comment puis-je vous aider aujourd'hui?'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call language detection with no API key setup, especially useful in agentic pipelines that process multilingual text and need to route, filter, or translate content based on its language. Ideal for workflows that don't justify a dedicated NLP subscription.

## Known failure modes

- Empty or very short input text may result in low-confidence or incorrect detection
- Mixed-language text may return only the dominant language or fail to detect accurately
- Extremely rare or low-resource languages may not be recognized
- Invalid or malformed request body returns a 400 error
- Payment failure or insufficient USDC balance returns a 402 error
