The YouTube Data API uses a [quota system](https://developers.google.com/youtube/data/determine_quota_cost.md.txt) to
ensure that developers use the service as intended and that they don't create
API clients which unfairly reduce service quality or limit access for others.

Projects that enable the YouTube Data API have a default quota allocation of
100 `search.list` calls, 100 `videos.insert` calls, and 10,000 units per day combined for all other endpoints. You can see your quota usage on
[Quotas](https://console.cloud.google.com/iam-admin/quotas) page in the Google Cloud console.

If you would like to request additional quota beyond the default allocation, you
must first complete an audit to show that your project is in compliance with the
[YouTube API Services Terms of
Service](https://developers.google.com/youtube/terms/developer-policies). This
gives YouTube visibility into the intended use cases of large projects and
ensures that YouTube's API services are being used in a manner that is free from
abuse. Visit [this
link](https://developers.google.com/youtube/terms/developer-policies-guide) for
additional details on complying with YouTube's Developer Policies.
