# Usage Limits

## Quota limitations

The Knowledge Graph API Search API allows developers a quota of up to 100,000 (one hundred thousand) read calls per day per project at no charge. We believe this meets the needs of the vast majority of developers.

## Requesting additional quota

It's also possible to request a higher quota from the APIs Console.

1. Go to the [quota page](https://console.developers.google.com/apis/api/kgsearch/quotas) in the Google API Console.
2. Click **Apply for higher quota**.
