Creating a Validation Function

Create a new file lib/nofakemails.ts:

export async function validateEmail(email: string) {
  const response = await fetch(
    `https://api.nofakemails.com/v1/email/${encodeURIComponent(email)}`,
    {
      headers: {
        'X-API-Key': process.env.NOFAKEMAILS_API_KEY!,
      },
    }
  )

  if (!response.ok) {
    throw new Error('Validation failed')
  }

  return response.json()
}
Copy

Using in a Server Action

'use server'

import { validateEmail } from '@/lib/nofakemails'

export async function checkEmail(formData: FormData) {
  const email = formData.get('email') as string
  const result = await validateEmail(email)

  if (result.disposable) {
    return { error: 'Disposable emails are not allowed' }
  }

  return { success: true }
}
Copy
