## 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 api-strale-io-8d65591e
```

Example prompt: What language is this text written in, and how confident are you? — 'Bonjour, je m'appelle Marie et j'habite à Paris.' Give me the top language and any close alternatives.

## When to prefer this

Choose this endpoint when you need fast, lightweight language identification across a broad set of 170+ languages and only need the top result with confidence score plus alternatives — particularly useful for routing, filtering, or tagging multilingual user content before downstream processing.

## Known failure modes

- Text too short — if input is below min_length (default 10 chars), detection may be unreliable or return low confidence
- Ambiguous/mixed language text — multilingual input may produce low confidence scores or incorrect primary language
- Empty or missing 'text' query parameter — returns 400 or validation error
- Very short common words may match multiple languages with near-equal scores
- Rare or unsupported languages may fall back to a close linguistic relative

## How this service works

Detect the language of input text. Returns top language with confidence score, plus alternative possibilities. Supports 170+ languages via trigram analysis.

## Output

Returns the top detected language (e.g. 'French') with a confidence score between 0 and 1, along with a ranked list of alternative language possibilities. Coverage spans 170+ languages detected via trigram analysis.
