# Page through the Experiment's immutable Slot set

`GET /api/{org_id}/experiments/{experiment_id}/slots`

## Request

- Base URL: `https://api.openobserve.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://api.openobserve.ai/api/{org_id}/experiments/{experiment_id}/slots`
- Auth: API key in header `Authorization`
- TypeScript: <https://skmtc.dev/openobserve/apis/openobserve-api-http/docs/api/:org_id/experiments/:experiment_id/slots/get.ts> (a function with typed inputs; its response is checked against the schema)

Returns the exact Slots the Experiment pinned at creation, in cohort order, with the Dataset input, expected output, and metadata each one carries. A client-driven run iterates this rather than re-deriving the set from the Dataset, where the snapshot filter could drift.

## Path parameters

- `org_id` string, required
- `experiment_id` string, required

## Query parameters

- `from` integer, nullable
- `size` integer, nullable

## Response `200`

- object: One page of the immutable Slot set, in pinned cohort order.
  - `from` integer, required
  - `hasMore` boolean, required
  - `size` integer, required
  - `slots` ExperimentSlotBody[], required
    - `expectedOutput` unknown
    - `input` unknown, required
    - `logicalId` string, required
    - `metadata` unknown
    - `rowId` string, required
    - `trialIndex` integer, required
  - `total` integer, required

## Other responses

- `400`: Invalid page size
- `404`: Experiment not found
