We put these\nlimits in place to protect the system and its users.\n\nAccess to the API requires OAuth client credentials from a Google developers\nproject. This project must have the Photos APIs enabled as described in\n[Configure your app](/photos/overview/configure-your-app).\n\nTo learn more about appropriate use of this API, see the\n[Acceptable use policy](/photos/support/api-policy).\n\nGeneral quota limits\n--------------------\n\nThe quota limit for requests to the Photos APIs is 10,000 requests per\nproject per day. This includes all API requests, such as uploading, listing\nmedia, and applying filters, but not accessing media bytes from a base URL.\n\nThe quota limit for requests to access media bytes (by\n[loading a photo or video from a base\nURL](/photos/library/guides/access-media-items#base-urls))\nis 75,000 requests per project per day.\n\nIn addition to these limits there are other quotas that exist to protect the\nreliability and integrity of our systems. If you receive a 429 error, you've\nlikely hit one of these quotas. If you receive one of these errors, reduce the\nnumber of requests you are making over a given time period. For more\ninformation, refer to [retrying failed\nrequests](/photos/overview/best-practices#retrying-failed-requests) and\n[exponential\nbackoff](/photos/overview/best-practices#exponential-backoff).\n\n### Checking quota usage\n\nTo see how much of your available quota you have used, and to view or change\nusage limits for your project, visit the\n[Quotas page](https://console.cloud.google.com/iam-admin/quotas?service=photoslibrary.googleapis.com)\nin the Google API Console and select either **Photos Picker API** or **Photos\nLibrary API**.\n\n### Exceeding quota limits\n\nIf the quota of requests to the Photos APIs is exceeded, the API returns\nan error code 429 and a message that the project has exceeded the quota. For\nmore information, see the [Terms of\nService](https://developers.google.com/terms/).\n\n### Requesting additional quota\n\nThe Google Photos partner program is geared towards large consumer\napplications that require increased quota limits. If you believe your\napplication belongs in this category, [express interest in the\npartner program](/photos/partner-program/overview).\n\nPhoto storage and quality\n-------------------------\n\nAll media items uploaded to Google Photos using the API are stored in\nfull resolution at [original\nquality](https://support.google.com/photos/answer/6220791). They count toward\nthe user's storage.\n| **Note:** If your uploads exceed 25MB per user, your application should remind the user that these uploads will count towards storage in their Google Account."]]
