Amazon ECR Public endpoints and quotas
The following are the service endpoints and service quotas for this service. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more information, see AWS service endpoints. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see AWS service quotas.
Service endpoints
The ecr-public and api.ecr-public endpoints are used for calls
to the Amazon ECR Public API. API actions such as DescribeImages and
CreateRepository go to this endpoint. While the two endpoints function the
same, the api.ecr-public endpoint is recommended and the default when using the
AWS CLI or AWS SDKs.

| Rate of BatchCheckLayerAvailability requests | Each supported Region: 200 per second |
Yes |
The maximum number of BatchCheckLayerAvailability requests that you can make per second in the current Region. When an image is pushed to a repository, each image layer is checked to verify if it has been uploaded before. If it has been uploaded, then the image layer is skipped. |
| Rate of CompleteLayerUpload requests | Each supported Region: 10 per second |
Yes |
The maximum number of CompleteLayerUpload requests that you can make per second in the current Region. When an image is pushed, the CompleteLayerUpload API is called once per each new image layer to verify that the upload has completed. |

When an image is pushed, the InitiateLayerUpload API is called once per image layer that has not already been uploaded. Whether or not an image layer has been uploaded is determined by the BatchCheckLayerAvailability API action. |
| Rate of PutImage requests | Each supported Region: 10 per second |
Yes |
The maximum number of PutImage requests that you can make per second in the current Region. When an image is pushed and all new image layers have been uploaded, the PutImage API is called once to create or update the image manifest and the tags associated with the image. |
| Rate of UploadLayerPart requests | Each supported Region: 260 per second |
Yes |
The maximum number of UploadLayerPart requests that you can make per second in the current Region. When an image is pushed, each new image layer is uploaded in parts and the UploadLayerPart API is called once per each new image layer part. |
