# Quotas

> View resource quotas for Chainstack subscription plans including maximum nodes, networks, API request limits, and concurrent WebSocket connection counts.

## Quotas and notifications

Each Chainstack’s subscription plan has its own quota that represents the allocated resources and usage limits that users can spend within their chosen plan.

In addition to the allocated quota, Chainstack also offers an extra usage setting. With it enabled, if you exceed your allocated quota, you can continue using Chainstack's services seamlessly, with any additional usage being automatically charged at the applicable rates.

Visit Chainstack’s [pricing page](https://chainstack.com/pricing/) to get familiar with a quota for each plan and extra usage costs. See [Manage your billing](/docs/manage-your-billing#manage-the-extra-usage-setting) on how to enable or disable the extra usage setting.

Quota spending can vary depending on the combination of services that you use. Service cost is reflected in [request units](/docs/request-units#what-are-request-units).

You will receive at least two email notifications:

* On using up 80% of your plan's quota
* On using up 100%
