# List experiments

`GET /v2/experiments`

List experiments a user has access to.

By default, lists every accessible experiment across all spaces the caller
can read, including experiments that are not associated with a dataset.

To narrow the results, provide at most one of:
- `dataset_id` — only experiments run on that dataset.
- `space_id` — only experiments in that space (with or without a dataset).

Providing both `dataset_id` and `space_id` is a validation error.

<Note>This endpoint is in beta, read more [here](https://arize.com/docs/ax/rest-reference#api-version-stages).</Note>

## Query parameters

- `dataset_id` string — A universally unique identifier (base64-encoded opaque string).
- `space_id` string — A universally unique identifier (base64-encoded opaque string).
- `name` string
- `limit` integer
- `cursor` string

## Response `200`

Returns a list of experiment objects

- ListExperimentsResponse
  - `experiments` Experiment[], required — A list of experiments
    - `id` string, required — Unique identifier for the experiment
    - `name` string, required — Name of the experiment
    - `space_id` string, required — Unique identifier for the space this experiment belongs to
    - `dataset_id` string, nullable — Unique identifier for the dataset associated with this experiment. Null if the experiment isn't associated with a dataset.
    - `dataset_version_id` string, nullable — Unique identifier for the dataset version associated with this experiment. Null if the experiment isn't associated with a dataset.
    - `created_at` string, date-time, required — Timestamp for when the experiment was created
    - `updated_at` string, date-time, required — Timestamp for the last update of the experiment
    - `experiment_traces_project_id` string — Unique identifier for the experiment traces project this experiment belongs to (if it exists)
    - `integration_id` string, nullable — Identifier (base64) of the agent integration that backs this experiment, as returned by the integrations API. Null for non-agent experiments (for example, SDK or Playground experiments).
  - `pagination` PaginationMetadata, required — Cursor-based pagination metadata. Use `next_cursor` in the subsequent request's `cursor` query parameter.
    - `next_cursor` string — Opaque cursor for fetching the next page. Treat as an unreadable token. Present when `has_more` is true; omitted when `has_more` is false.
    - `has_more` boolean, required — True if another page of results is available.
