Some of the Let's Encrypt ACME clients (Certbot, acme.sh, Dehydrated, etc.) make API hooks available to use with DNS providers. Using these clients, you can automate the renewal of your certs, but if you want to push the new certs to your DNS provider (such as Ezoic) you still have to do so manually.

This request is to build an API that these clients can use for two common use cases:
1. Create records to respond to dns-01 challenges
2. Automate upload of certificate to Ezoic
