Get widget chart data

Returns chart data for one or more widget types in the requested time range.

Workflow

GET /widgets — list valid widget slugs (data[].id).
POST /applications/{applicationId}/widget-data — pass those slugs as body types (array of strings), plus start and end (ISO 8601 UTC, inclusive; end must be on or after start).

Request body

Field	Required	When to use
`types`	yes	Widget slugs from `GET /widgets` `data[].id` (e.g. `sessions-evaluated`, `guardrail-latency`)
`start`, `end`	yes	Time range for the charts

Response

data — array of widget results in the same order as types. Each item includes:
- id — requested widget slug
- data — chart payload when successful; shape depends on the widget (see response examples)
- meta.source — category label for the widget data (see response examples)
- meta.type — resolved widget type (e.g. token-usage may map to tokens-analysis)
- message / code — present when that widget could not be loaded (unknown_type, unsupported, upstream)

Time-bucketed series are zero-filled between start and end. Bucket granularity (hour / day / week / month) is chosen from the range length.
