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.
- Go to the quota page in the Google API Console.
- Click Apply for higher quota.
