GET Snapshots & Changes

Read a monitor's captured snapshots, detected changes, and page bodies

Every check stores a snapshot. When a snapshot differs from the previous one, a change is recorded. These endpoints let you read that history.

GEThttps://api.anakin.io/v1/monitors/{id}/changes

List detected changes for a monitor, newest first (up to 200).

Field	Type	Description
`changedAt`	string	When the change was detected.
`summary`	string \| null	Human-readable summary (AI-generated when `aiMode` is on).
`diffJson`	object	Structured diff (see below).

diffJson fields

Field	Type	Description
`type`	string	`specific_data` or `full_page`.
`changedFields`	string[]	Field keys that changed (`specific_data`).
`before` / `after`	object	Extracted values before/after (`specific_data`).
`beforeSnapshotId` / `afterSnapshotId`	string	Snapshot IDs for a `full_page` text diff — fetch each side's body via the content endpoint below.
`stats`	object	`{ "adds": number, "dels": number }` — line counts for `full_page` diffs.
`aiMeaningful`	array	AI-curated substantive changes, each `{ description, before, after }` (present in `aiMode`).

    }
  ]
}

Field	Type	Description
`contentHash`	string	Hash of the compared content — identical hashes mean no change.
`extractedData`	object \| null	Extracted fields (`specific_data` mode).

To read a full_page snapshot's stored body (for rendering a text diff), call the snapshot content endpoint below with the snapshot's id — you never handle a storage path.

GEThttps://api.anakin.io/v1/monitors/{id}/snapshots/{snapshotId}/content

Fetch the stored page body for a full_page snapshot — use it to render before/after text diffs. Returns an empty body for specific_data snapshots (their data is in extractedData).

Response

200 OK

{
  "available": true,
  "content": "# Home page content…",
  "capturedAt": "2026-01-01T12:00:00Z",
  "contentHash": "a1b2c3…"
}

Field	Type	Description
`available`	boolean	`false` when no body is stored (e.g. `specific_data`, or storage not configured).
`content`	string	The captured body in the monitor's `watchFormat`. Empty when `available` is `false`.
