Request Limits

Rate Limits

All Cosmic Buckets have a rate limit of 500 API requests per second per IP address. This only applies to non-cached API requests. Non-cached API requests include any initial GET request, all POST, PUT, PATCH, and DELETE requests to the API. This does not apply to any files or images served via the Cosmic CDN or imgix CDN.

Size Limits

All Cosmic POST requests have a body size limit of 6MB. At this time media cannot be uploaded via the GraphQL API.

Optimizations

All requests allow gzip ecoding. If connecting to the API directly, adding Accept-Encoding: gzip can dramatically reduce response time and size. This is added by default on all Cosmic open source clients.
