Metadata API

Metadata API

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

/v1.json

Retrieve the entire metadata tree as a JSON document.
