# Quotas and Limits

The CSS API imposes quotas and hard limitations on some
features. The quotas and limits shown in the following table are provided
solely to assist you in
developing applications that use the CSS API. All quotas and
limits are subject to elimination, reduction, or change at any time, without
notice.

## Check your quota usage

You can check your current quota usage using the
[`accounts.quotas.list`](https://developers.google.com/comparison-shopping-services/api/reference/rest/v1/accounts.quotas/list)
method. This method lets you retrieve the current quota usage for your account.
See this [sample](https://developers.google.com/comparison-shopping-services/api/code-samples/quotas/list-quota-groups)
to learn how to perform this quota retrieval.

## Quota policy

Don't update your products if they are unchanged. If you need to send updates to
keep a product from expiring, doing so once a week is enough.

## Method call quotas

The following limits are the default method call quotas for CSS Center
accounts.

- Users exceeding the per minute quota receive `quota/request_rate_too_high` errors.
- Users exceeding the per day quota receive `quota/daily_limit_exceeded` errors.

Here are some things to keep in mind:

- The quotas here are per-method. For example, the `get` method has a separate quota of calls from the `update` method, though the size of those quotas is the same.
- Calls count against the quota of the affected account. For product related operations this will be the CSS Domain account, for account list operation it depends on the account the list is called on.

Here are the default limits:
