## 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 apexapi-text-language-detection-548da373 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a quick, pay-per-call language detection with no API key setup, especially in agent workflows that handle multilingual text input and need to route or process text differently by language. Suitable for single-text language identification rather than bulk processing.

## Known failure modes

- Empty or missing query string returns an error
- Text too short to reliably detect language may return low confidence or incorrect result
- Mixed-language text may produce ambiguous or incorrect detection
- API payment failure due to insufficient USDC on Base
- Service unavailable or timeout from the hosted Vercel instance
