DNS A Lookup API

Perform live DNS A record lookups for any domain via REST API. Returns all IPv4 addresses and their TTL values from a real DNS resolution — useful for infrastructure monitoring, network diagnostics, and verifying DNS configuration after changes.

How it works

POST a domain name. The API performs a live DNS query using Node.js's dns.resolve4() (with TTL option), returning all A records with their IPv4 addresses and TTL values in seconds.

Use cases

Verify DNS A record configuration after pointing a domain to a new server
Monitor DNS changes as part of infrastructure automation
Check if a domain resolves before making HTTP requests in agent workflows
Audit A records across multiple domains for security reviews

Examples

Three real-world scenarios showing how developers use DNS A Lookup in production.

Example 1

Verify DNS after migration

Check A records after pointing a domain to a new server to confirm propagation.

curl -X POST https://slopshop.gg/v1/net-dns-a \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain": "example.com"}'

Example 2

Pre-flight check in agent

Verify a domain resolves before making HTTP requests in an automation workflow.

curl -X POST https://slopshop.gg/v1/net-dns-a \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain": "api.github.com"}'

Example 3

Audit infrastructure DNS

Check that all production subdomains resolve to expected IPs.

curl -X POST https://slopshop.gg/v1/net-dns-a \
  -H "Authorization: Bearer $SLOPSHOP_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain": "app.myproduct.com"}'

Code examples

curl

curl -X POST https://slopshop.gg/v1/net-dns-a \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input": "your data here"}'

Python

import requests

response = requests.post(
    "https://slopshop.gg/v1/net-dns-a",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={"input": "your data here"}
)
result = response.json()
print(result["data"])

Node.js

const response = await fetch("https://slopshop.gg/v1/net-dns-a", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ input: "your data here" })
});
const { data } = await response.json();
console.log(data);

CLI

# Install the Slopshop CLI
npm install -g slopshop

# Set your API key
export SLOPSHOP_KEY=your_api_key

# Call net-dns-a
slop net-dns-a '{"input": "your data here"}'
