# 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
Except for the upload media endpoint, which allows up to 900MB
files to be uploaded, all Cosmic request and response payloads have a size limit of 6MB
.
# 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.
