# ONE Engine Text Normalize Slug

> ONE Engine Text Normalize Slug is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-02).

Converts arbitrary text into a URL-safe slug by normalizing and transforming it into a lowercase, hyphen-separated string.

## 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 one-engine-text-normalize-slug-7439f132 -d '<json body>'
```

Example prompt: Can you slugify this text for me so I can use it as a URL path: 'The Best Coffee Shops in New York City (2024 Edition)'?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call slug generation utility without setting up your own text processing pipeline. Ideal for AI agents that occasionally need to slugify strings on-the-fly without maintaining a local library. At $0.0015 USDC per call it is cost-effective for infrequent or dynamic slug generation needs.

## Known failure modes

- Text exceeds 50000 character limit — request rejected
- Empty text input — may return empty slug or error
- Payment failure via x402 — 402 response if USDC payment not provided or insufficient
- Network/worker timeout for very large inputs near the character limit

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the normalized slug — a lowercase, hyphen-separated, URL-safe version of the input text with special characters and spaces removed or replaced.
