## Response `200`

DNS snapshot captured

    - `type` 'A' | 'AAAA' | 'CNAME' | 'MX' | 'TXT' | 'NS' | 'SRV' | 'CAA' | 'TLSA', required: DNS record type. TLSA publishes a DANE record; its value is the rdata 'usage selector matching-type hex-data'.
    - `name` string, required: Record name (@ for root, or subdomain, e.g. _443._tcp for TLSA)
    - `value` string, required: Record value (IP address, hostname, or TLSA rdata like '3 1 1 abc123...')
    - `ttl` integer, required: Time to live in seconds
    - `priority` integer: Priority value (required for MX records)
    - `required` boolean: False when the zone Domani manages for the domain cannot hold the record (a TXT longer than the registrar accepts); such a record is shown but not needed for mail to work. Absent on plain zone records.

  - `sources` string[]
  - `capturedAt` string, date-time
