API access to IP Tools

Try the Free API access to the IP Tools. The purpose of providing these tools accessible via an API is to make it as easy as possible to quickly get access to information that can assist when assessing the security of an organizations network.

The output from the API is basic text, you can access the API using curl, a web browser or a scripting language of your choice such as php or python.

Using the API is straight forward, the target system IP address or hostname can be added to the q= parameter. No key or sign-up is required to access the API.

If you are a registered user you can access an API key in the user control panel. Access with the API key must use HTTPS.

Example request with curl and a valid API Key:

curl https://api.hackertarget.com/dnslookup/?q=hackertarget.com&apikey=plmoknijbuhvygvtrgedsfghhhhkjhkhfsk
