Cloudinary’s image handling APIs do not limit the number of uploads, transformations and downloads (views). The only limits are the total number of images managed in your Cloudinary account, monthly bandwidth and total storage used that are defined by the plan you're currently signed to.
Cloudinary’s Admin APIs (listing & deleting resources) are limited in default to 500 requests per hour for our Free plan.
From our Basic plan onward the Admin API calls limit is automatically increased to 2000 calls per hour.
The limit can be raised to a higher limit for our Premium plan.
