dns_apertodns

ApertoDNS provides free dynamic DNS for .apertodns.com subdomains.

First, get your API key from the ApertoDNS dashboard.

export APERTODNS_API_KEY="apertodns_live_xxxxxxxx"

To issue a certificate:

acme.sh --issue --dns dns_apertodns -d myhost.apertodns.com

For wildcard certificates:

acme.sh --issue --dns dns_apertodns -d myhost.apertodns.com -d '*.myhost.apertodns.com'

The APERTODNS_API_KEY will be saved in ~/.acme.sh/account.conf and reused for future requests.

Optionally, you can specify a custom API URL:

export APERTODNS_API_URL="https://api.apertodns.com"
