To illustrate the practical application of these SecurityTrails alternatives, let's consider a common task: performing a DNS lookup. Below, we demonstrate how to use Spyse's API for this purpose, showcasing its capabilities in asset discovery.

Using Spyse API for DNS Lookup

First, you will need to sign up for an API key on Spyse. Once you have your key, you can use the following command to perform a DNS lookup for a specific domain:

curl -X GET "https://api.spyse.com/v4/data/dns?key=YOUR_API_KEY&domain=example.com"

This command sends a GET request to the Spyse API, retrieving DNS records for example.com. The response will include information such as:

• A records
• MX records
• NS records

With this data, security professionals can assess potential vulnerabilities associated with the domain. Additionally, you can utilize similar API calls for ThreatHunter or Netlytic, depending on your specific requirements.

In summary, while SecurityTrails remains a strong option, exploring alternatives like Spyse, ThreatHunter, and Netlytic can provide enhanced features and flexibility, allowing organizations to better secure their digital assets and infrastructure in 2026.
