Your first HTTPS monitor is free, forever. Pay per host after that, with no minimum commitments.
A "host" is any TLS-enabled endpoint: website, mail server, API, database, or any other service using SSL/TLS. You pay only for what you monitor, billed daily. Add or remove hosts anytime and billing adjusts automatically. No contracts, no minimums.
Every account gets one HTTPS monitor free, forever, with no credit card required. Monitors on other protocols, such as STARTTLS for SMTP or LDAP, are billed at the standard rate.
