Logs v2.1

Get the Latest Log Entries

Gets the latest 100 log entries in a Project. Results are sorted descending by timestamp and _id. Supports cursor-based pagination via opaque base64url tokens returned in nextCursor and previousCursor. The total field is always -1 because counting rows in this collection is intentionally skipped for performance reasons. If you provide an invalid cursor value, a 400 error will be returned. When the request header x-cognigy-log-model-version is set to v2, the response items use the V2 shape with a nested metadata object instead of a top-level type field.
