Input Variables

Variable Name Input Details
apikey Your unique API Key. If you don't have one, please first get an API Key.
job_type dns_lookup
job_input This is the domain that you want to submit

Output Variables

Variable Description
domain The input domains relating to the DNS records
ARecords IPv4 A Records
AAAARecords IPv6 AAAA Records
CName CName Records redirect one domain to another
TxtRecords TXT Records provide arbitrary text information associated with a domain
MxRecords MX Records define the mail server responsible for a domain
  • Key - Hostname of the MX mail server domain
  • Value - The priority of the MX entry, lower value is a higher priority
SrvRecords SRV Records specify the location of servers for specific services within a domain
  • target - The domain name of the server providing the service.
  • port - The TCP or UDP port on which the service is to be found.
  • priority - The priority of the target host, lower value means more preferred.
  • weight - A relative weight for records with the same priority, higher value means higher chance of getting selected.

Output Examples

{"domain":"servya.com","ARecords":[""],"AAAARecords":[],"CName":"No CNAME record found","TxtRecords":["v=spf1 +a +mx -all"],"MxRecords":[{"Key":"mail.servya.com","Value":10}],"SrvRecords":[]}

Servya API Instructions for Developers

To start testing your implementation and the provided code examples you will first need to acquire an API key.

When you have your API key you will want to visit the documentation for the individual tools to get the API endpoints, inputs, outputs and examples.

We have code examples in lots of popular languages but if you need some help in a different language you can get in touch for some advice.

The API uses simple HTTP post requests and JSON to keep the process of interacting with the API and handling the data returned as simple as possible.

See the list of tools on this page for a direct link to the documentation for the tools.

We have code examples for 6 major programming languages below to aid the integration with your platform.

How to use the API for End Users

Integrating Servya into a supported tool is really simple!

You will first need to get an API key for Servya and then copy it into your software.

From our side, that is all you need to do. Your software should now be able to use the data from our tools.

Servya API Code Examples

Below you'll find code examples in various programming languages. These examples demonstrate how to interact with our API, making it easier for you to integrate our services into your applications. Simply click on the headers to view the code in your preferred language and see how you can quickly get started.
