## Is there a rate limit on the API?

For Places Aggregate API, there is a default rate limit of
1,200 queries per minute.

## What is the difference between 'included_primary_types' and 'included_types' in the TypeFilter?

- `included_primary_types`: Filters for places where the specified types are their main or primary category. These places might also have other secondary types.
- `included_types`: Filters for places that have the specified types as any of their categories, regardless of whether it's the primary or secondary type.

For example, a search using `included_primary_types` set to `restaurant` would
return places whose primary function is to serve food, whereas `included_types`
set to `restaurant` would return places that serve food even if they have
another primary category, such as a `museum` with a `cafe`.

## How do I define a custom search area that isn't a circle?

You can define a custom search area using a polygon. Provide a list of latitude
and longitude coordinates that define the vertices of a single polygon in a
counter-clockwise order. The first and last coordinates *must* be the same to
close the polygon.
