In this tutorial, you will learn basic Vultr API v2 usage with the curl command and also with Python. By the end of this tutorial, you will know how to deploy a Vultr VPS from via the API and get it’s IP address.

Vultr API with Curl

In order to deploy a Vultr server, you need three pieces of information.

  1. Region
  2. Plan
  3. Operating system

Let’s determine the possible values for each of these, and choose one that meets our needs.

First, let’s determine the valid regions.

curl --location --request GET ''

The curl command will return a dictionary with all the possible regions. In this case, let’s choose syd for the datacenter in Sydney.

Next, let’s figure out what the options are for plans.

curl --location --request GET ''

The curl command will return a dictionary with all the possible Vultr plans. Let’s choose a basic vc2-1c-1gb instance.

Finally, let’s find out which operating systems are available.

curl --location --request GET ''

The curl command will return a dictionary with all the possible operating systems. I want Ubuntu 20.04 so the  id associated with that is 387.

With this information, we can create spin up a Vultr server with the curl command.

curl --location --request POST '' \
--header 'Authorization: Bearer <your-api-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
    "region" : "syd", 
    "plan" : "vc2-1c-1gb", 
    "label" : "Hello from Curl",
    "os_id" : 387

Feel free to choose your own values for region, plan, label, and os_id. Also, replace <your-api-key> with your actual Vultr API key.

The output from the curl command will contain information about your new server instance. Please take note of the instance id. We will use this next.

With your instance id, query the Vultr API again for information about your instance.

curl --location --request GET '<your-instance-id>' \
--header 'Authorization: Bearer <your-api-key>'

In the output, you will find the main_id field with the value of your instance’s IP address.

Vultr API with Python

We can use Python to interact with the Vultr API. To do this, we will primarily be using the requests Python library.

Based on the information from above, here is a full Python script that creates a Vultr VPS and gets it’s IP address.

import time
import requests

# private constants
api_key = "<your-api-key>"

# api url
url = ""

headers = {"Authorization": "Bearer {}".format(api_key),
           "Content-Type": "application/json"}
data = {
    "region" : "ewr", 
    "plan" : "vc2-1c-1gb", 
    "label" : "Hello from Python",
    "os_id" : 387
response =, json=data, headers=headers)
instance_id = response.json()['instance']['id']

# wait a minute until the VPS is ready

# get instance ip address
instance_url = "{}/{}".format(url, instance_id)
instance_response = requests.get(instance_url, headers=headers)
ip_address = instance_response.json()['instance']['main_ip']

For more context, here is a video tutorial about interacting with the Vultr API that I created.
