Headers

x-extend-api-version"2025-04-21"Optional
API version to use for the request. If you do not specify a version, you will either receive a `400 Bad Request` or be set to a previous legacy version. See [API Versioning](https://docs.extend.ai/2025-04-21/developers/api-versioning) for more details.
x-extend-workspace-idstringOptional
The workspace ID to target. **Required** when using an organization-scoped API key; optional for workspace-scoped keys (the key is already tied to a workspace). See [Authentication](https://docs.extend.ai/2025-04-21/developers/authentication) for details on API key scopes.

Query parameters

sortByenumOptionalDefaults to updatedAt
Sorts the evaluation set items by the given field.
Allowed values:
sortDirenumOptionalDefaults to desc
Sorts the evaluation set items in ascending or descending order. Ascending order means the earliest evaluation set is returned first.
Allowed values:
nextPageTokenstringOptional
The token used to fetch the page of results from a previous request. We use cursor based pagination and will return a `nextPageToken` in the response if there are more results. Note that if other parameters are changed in subsequent requests, you may receive inconsistent data. example: `"xK9mLPqRtN3vS8wF5hB2cQ==:zWvUxYjM4nKpL7aDgE9HbTcR2mAyX3/Q+CNkfBSw1dZ="`
maxPageSizeintegerOptional1-1000Defaults to 10
The maximum number of results to return in the response. You may receive less than this number if there are fewer results than the maximum.
