how to use api key with axois code example

Example 1: Using axios send a GET request to the address:

// GET request for remote image
axios({
  method: 'get',
  url: 'http://bit.ly/2mTM3nY',
  responseType: 'stream'
})
  .then(function(response) {
  response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
});

Example 2: Using axios send a GET request to the address:

// Make a request for a user with a given ID
axios.get('/user?ID=12345')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

// Optionally the request above could also be done as
axios.get('/user', {
    params: {
      ID: 12345
    }
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });
