Let me rephrase my question. How exact must the address input be? Do I need to include unit numbers? What if the street number is off by a few due to the layout of a plaza?

Using Maps or Web Search APIs, I can find approximate locations for certain businesses based on my input. Can your API work in a similar manner?

It is supposed to work if you even don't include unit number or a house number is a bit off. We analyze other signals too, so if the address is a bit off, the API is still supposed to mark a place as existing
