## Endpoint reference

### Stem Text API

`GET https://api.eu.apyhub.com/skycraft/language-detection-text-tagging/stem-text` · 20 atoms · accepts `application/json` · returns `application/json`

| Parameter | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `text` | query | string | yes | Example: `The laziest dogs are jumping over the quicker brown foxes.`. |

#### Quickstart

Call this endpoint with your ApyHub API key:

```bash
curl "https://api.eu.apyhub.com/skycraft/language-detection-text-tagging/stem-text?text=The%20cats%20are%20running%20in%20the%20gardens." \
  -H 'apy-token: $APY_TOKEN'
```

##### What you'll get back 

```json
{
  "original": "The cats are running in the gardens.",
  "stemmed": "The cat are run in the garden."
}
```

}
```

## About

## What it does
Language Detection & Text Tagging API runs core linguistic preprocessing on a piece of text. Send a sentence or passage as a single `text` query parameter and get back structured JSON: the detected language with confidence scores, a stemmed version of the text, or the text annotated with part-of-speech tags.

`Detect Language` takes `text` and returns a list of candidate languages, each with a `language` code and a `confidence` score, most likely first; it works best on a full sentence or more. `Stem Text` takes `text` and returns the `original` alongside a `stemmed` version where each word is reduced to its root form, so "jumping" and "jumped" match. `Tag Part of Speech` takes `text` and returns `tagged_text`, the same text with a grammatical tag attached to each word.

Language Detection & Text Tagging API is a good fit when you need to route user content by language, normalize text before search indexing or matching, or feed grammatical structure into a lightweight NLP pipeline without hosting your own models.
