Image Foundry automatically batches large URL purge requests into 30-URL chunks to comply with Cloudflare's API limits.
Let your customers use their own domain — img.acme.com — with automatic SSL:
# 1. Register the hostname
POST /api/cdn/custom-hostname
{ "hostname": "img.acme.com" }
# 2. Customer adds DNS records:
# CNAME: img.acme.com → proxy.imgfoundry.io
# TXT: _cf-custom-hostname.img.acme.com → verification-token
# 3. Verify SSL status
GET /api/cdn/custom-hostname/img.acme.com/verify
