# Duo Data Utilities – Text Slugifier

> Duo Data Utilities – Text Slugifier is a paid API for AI agents from api.duoleads.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-02).

Converts arbitrary text into a URL-safe slug with locale-aware transliteration, accent decomposition, separator options, length truncation, and stop-word removal.

## 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 duo-data-utilities-text-slugifier-dacbd631
```

Example prompt: Can you slugify the text 'Crème Brûlée – Ærøskøbing Straße 42' for me using a hyphen separator, keeping it under 60 characters, lowercase, with German locale folding?

## When to prefer this

Choose this endpoint when you need deterministic, locale-aware slug generation from internationalized text — especially when dealing with German umlauts, Scandinavian letters (Æ, Ø, Å), Turkish dotless-i, or ligatures that break under plain NFD normalization. It is preferable over generic slugify libraries when you need fine-grained control over separator character, maximum length with word-boundary truncation, case preservation, and visibility into exactly what was removed or transliterated during conversion.

## Known failure modes

- Text exceeds 2048 character limit — request rejected
- Invalid max length value outside 1–512 range — validation error
- Unsupported language code — may fall back to locale-neutral processing
- Empty text input — may return empty slug or error
- Unsupported separator character — validation error

## How this service works

Turn arbitrary text into a URL-safe slug. Decomposes accents, transliterates German umlauts, Scandinavian and Turkish letters, the ligatures that lose meaning under plain NFD, and Cyrillic (Russian, Ukrainian, Belarusian, Bulgarian, Serbian, Macedonian; language from lang or inferred from the letters). Lowercases, collapses separators, truncates on a word boundary. Returns the slug plus what was removed.

## Output

Returns a JSON object containing the generated slug string, its character length, a list of characters that were removed during processing, a boolean indicating whether truncation occurred, the original source text length, and an array of transliteration mappings showing which characters were converted and to what.
