theHarvester is a tool used to harvest/gather sensitive information that can help in determining a company's external threat landscape on the internet.

 TheHarvester Public engine

One of the interesting things about ‘theHarvester’ is that it supports more than one public source to harvest information. These sources appear to be more than 20+ public sources supported by the information gathering tool.

And this public sources that require API include:

• SecurityTrails
• Hunter
• GitHub
• Shodan
• bingapi
• Spyse
• Intelx

But if you don't have API you can still use some other public sources
