Reverse IP Lookup API documentation

 IP Ninja allows to perform several operations tied to OSINT such as:

• reverse IP lookup
• IP geolocation
• Subdomain enumeration
• ASN lookup
• Reverse ASN lookup

The API is well documented as they provide a swagger documentation here:

https://ip-ninja.com/api/docs

I also noticed the API is documented on both SwaggerHub and RapidAPI.

To use the API you just need to obtain the API key by registering to the website and subscribing for a plan (or use the 7 days trial period).

Once done, you obtain the API key from your dashboard. You just have to pass the API key within the X-Ninja header to be authenticated on the API.

You can use cURL for example:

curl https://ip-ninja.com/api/vi/subdomains/google.com -H "X-Ninja: your_api_key"

Very easy stuff.

Results are very good and the API is fast enough.

The Shuriken plan is very interesting for bug bounty hunters.
