Vultr: High Performance SSD Cloud.

Overview

The Vultr Metadata API is a service available to all Vultr cloud servers and allows any instance to query information about itself. With additional scripting, this service enables developers to create self-configuring instances. The API functions described in this document will only return information about the calling instance.

API Endpoint: http://169.254.169.254/v1/

HTTP Response Code	Description
200	Function successfully executed.
404	Invalid location. Check the URL that you are using.
405	Invalid HTTP method. Check that the method (POST\|GET) matches what the documentation indicates.
500	Internal server error. Try again at a later time.
503	Service is currently unavailable. Try your request again later.

Using the API

Function calls are performed over standard HTTP with no authentication.
There are two types of endpoints: indexes and values. Indexes end with a "/" and return a listing of values for the given path. Values print the value for the given path in plain text.
Each endpoint in this document includes a cURL example. If cURL is installed on your virtual machine, you can use the example to test an endpoint.

Metadata

Index (JSON)

/v1.json

Retrieve the entire metadata tree as a JSON document.
