The rule for a US licence
India recognizes an international driving permit for foreign visitors, valid for up to one year or until your visa expires, whichever comes first. Both documents must be produced together - the permit is not valid on its own.
Many visitors to India hire a car with a driver rather than self-driving, which removes the licensing question entirely and is common practice.
Live in India?
A licence issued in India is what you drive on at home - an IDP translates a foreign licence, so it does not apply to you here. If your licence is from somewhere else, check that licence country: the rule depends on where the licence was issued, not only on where you are driving.
At the rental counter
Self-drive rental agencies require the IDP. Driver-included hire is widely available and often costs little more.
What the permit covers
An International Driving Permit is a translation of your licence into a standard multilingual booklet, issued under the 1949 and 1968 road traffic conventions. It is not a licence, and it is never valid on its own: you carry it with your own licence, and police expect to see both.
It is issued against the vehicle classes already on your home licence, and it never adds one. If your licence does not cover motorcycles, an IDP does not let you ride a scooter in India; if it does not cover a heavier vehicle, the permit will not cover a camper or a minibus either. The permit restates what you already hold, in a form the local authorities can read.
