# Check slug availability

> Check whether a space slug is available for use

## Overview

`useCheckSlugAvailability` returns a callable function that verifies whether a slug is available in the current project. Useful for live validation in a space creation or settings form.

## Usage Example

```tsx theme={null}
import { useCheckSlugAvailability } from "@replyke/react-js";
import { useState } from "react";

function SlugInput() {
  const checkSlug = useCheckSlugAvailability();
  const [available, setAvailable] = useState<boolean | null>(null);

  const handleBlur = async (slug: string) => {
    const result = await checkSlug({ slug });
    setAvailable(result.available);
  };

  return (
    <div>
      <input onBlur={(e) => handleBlur(e.target.value)} />
      {available === false && <p>Slug is already taken.</p>}
      {available === true && <p>Slug is available!</p>}
    </div>
  );
}
```

## Parameters

<ParamField path="slug" type="string" required>
  The slug to check. Must match the slug pattern: letters, numbers, hyphens, and underscores (Unicode supported).
</ParamField>

## Returns

<ResponseField name="available" type="boolean">
  `true` if the slug is not currently in use within the project.
</ResponseField>
