domains

Required

One to 1,000 domains or URLs. Subdomains and URLs are reduced to their registrable domain with a pinned Public Suffix List. externalId is echoed for joins and is never sent to registries.

Type:object[]

Min. items:1

Max. items:1000

Mode

mode

Optional

snapshot returns the current observation without KVS state. monitor compares with the last complete successful observation and emits exact changes.

Type:string

Default:monitor

Options:

snapshotmonitor

Output mode

outputMode

Optional

changesOnly suppresses the redundant UNCHANGED event object; all keeps it. For batch safety, both modes still return one explicit status row per input.

Type:string

Default:changesOnly

Options:

changesOnlyall

Observe DNS records

includeDns

Optional

Observe normalized public A, AAAA, MX, NS and CAA records. TXT records are intentionally excluded. A DNS transport failure makes the observation PARTIAL and preserves prior state.

Type:boolean

Default:true

Observe TLS certificate

includeTls

Optional

Make one standard port-443 TLS connection and collect certificate identity, issuer and validity only. No vulnerability scanning. Disabled by default because many valid registrable domains do not serve TLS on the bare domain; a requested TLS failure makes the observation PARTIAL and preserves prior state.

Type:boolean

Default:false

Expiry warning thresholds

expiryWarningDays

Optional

Emit domain and TLS expiry warnings only when the remaining days cross one of these thresholds. Emitted warnings are remembered and reset after renewal.
