}

List all items in a specific evaluation set. Evaluation set items are the individual files and expected outputs that are used to evaluate the performance of a given processor in Extend.

This endpoint returns a paginated response. You can use the nextPageToken to fetch subsequent results.

Authentication

AuthorizationBearer

Bearer authentication of the form Bearer <token>, where token is your auth token.

Path parameters

idstringRequired

The ID of the evaluation set to retrieve items for.

Example: "ev_2LcgeY_mp2T5yPaEuq5Lw"

Headers

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 for details on API key scopes.

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="

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.

nextPageTokenstring

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.
