開発環境: /api → http://localhost:8000/api
開発環境以外: /api → https//example.com/api

にそれぞれアクセスを変更する設定です。
これで以下のようにホスト名を省略した記述が可能になります。
import Logo from '~/components/Logo.vue'

export default {
  components: {
    Logo
  },
  async asyncData(app) {
    const data = await app.$axios.$get('/api')
    return {
      data
    }
  }
}
