Frequently Asked Questions

WHOIS/RDAP, DNS, and Dashboard monitoring details.

What is Domain Monitoring?

Domain Monitoring is a signed-in, owner-scoped Dashboard product that watches configured WHOIS/RDAP and/or DNS sources for changes over time. It is not a bearer-token REST API.

What happens when a monitored value changes?

The Dashboard records a change timeline. When available, an event includes customer-facing previous and current values.

How are monitoring notifications sent?

Eligible email alerts are sent immediately. Entitled accounts can configure one signed outbound webhook endpoint for monitoring events.

Can I import a large set of domains?

Bulk import is available when your plan enables it. Monitoring capacity, imports, and webhooks depend on your plan and permissions.

What is the DNS Records API?

The DNS Records API returns live DNS records for a hostname through the authenticated REST API in structured JSON grouped by record type.

Which DNS record types are supported?

The supported DNS record types are A, AAAA, MX, NS, TXT, CNAME, SOA, and CAA.

How are DNS API requests counted?

Each accepted DNS lookup consumes one shared request credit, regardless of the number of requested record types.
