DNS Records

Check DNS records and subdomains

List all DNS Records (subdomains, A, MX, CNAME, TXT, etc) for a domain.

Subdomains are auto-disovered, and hints for more obscure ones can be sent to the API to check for.

Pro tip: use the "Accept" header to retrieve the DNS records in different types:

• "application/json" - get DNS Records as JSON objects

• "text/plain" - get DNS Records as text lines in 2 modes: wait for full response or read streamed lines as they are discovered (see JavaScript Fetch example below)

GET https://api.dmns.co/domains/{domain}/dns-records

Path Parameters

Name	Type	Description
domain*	String	Valid domain name

Query Parameters

Name	Type	Description
type	String	A, AAAA, MX, etc
apiKey	String	Your API Key
subdomain	String	Extra subdomain to check for

Headers

Name	Type	Description
Authorization	String	Your API Key
Accept	String	- "text/plain" (default): return DNS records as text lines - "application/json": return DNS records as JSON object

Examples

JS - fetch

const domain = 'openai.com'

// text/plain - get DNS records as they are discovered (stream)
fetch(`/domains/${domain}/dns-records?apiKey=_api_key_`)
    .then(async response => {
        if (response.ok) {
            const reader = response.body.getReader()
            const decoder = new TextDecoder()
            while (true) {
                const {done, value} = await reader.read();
                if (done) return;
                console.log(decoder.decode(value))
            }
        }
    })

// text/plain - wait for full response
fetch(`/domains/${domain}/dns-records?apiKey=_api_key_`)
    .then(response => response.text())
    .then(dnsRecords => {
        console.log('all DNS Records', dnsRecords)
    })

// application/json
fetch(`/domains/${domain}/dns-records?apiKey=_api_key_`, {
    headers: {
        accept: 'application/json',
    }
})
    .then(response => response.json())
    .then(dnsRecords => {
        console.log('all DNS Records', dnsRecords)
    })

JS - axios

import axios from 'axios'

const domain = 'github.com'
const { data: dnsRecords } = await axios(`https://api.dmns.co/domain/${domain}/dns-records?apiKey=_key_`, {
  headers: {
    accept: 'application/json'
  }
})

console.log('all dns records', dnsRecords)
