# Get Eval Document Fields

> One eval document's extracted values beside its ground truth

*Rate limit tier: **general**, 600 requests/min. See [Rate limits](/api-reference-v3/introduction#rate-limits).*

Shows, for one document of an [eval](/concepts/evals), each field's `extracted` value beside its `expected` ground-truth value. The extracted values are the ones the eval graded.

`document_packet_id` is the **dataset copy's** id, as [`GET …/evals/{eval_id}/accuracy/`](/api-reference-v3/evals/accuracy) returns it in `by_document_packet`. It is not the id of the production packet the document was added from.

A scalar field's values are scalars. For a field inside a list or an object, `extracted` and `expected` hold one value per row, in row order. `has_extraction` is `false` when the eval produced no extraction for the document; its `extracted` values are then `null`.

A document outside the eval, an unknown eval, or one on another workflow or organization returns `404 NOT_FOUND`.

## OpenAPI

openapi: 3.1.0
info:
  title: anyformat API
  description: >
    Document extraction and workflow automation API.


    AnyFormat lets you define extraction workflows that pull structured data
    from any document — PDFs, images, scanned files, or plain text. Upload a
    file, run it through a workflow, and get back structured fields with
    confidence scores and source evidence.


    ## Quick start


    See the [Quick start
    guide](https://docs.anyformat.ai/api-reference-v3/introduction) for a
    walkthrough.


    ## Authentication


    All endpoints (except `/health/`) require a Bearer token in the
    `Authorization` header:


    ```

    Authorization: Bearer <your-api-key>

    ```


    Get your API key from
    [app.anyformat.ai/api-key](https://app.anyformat.ai/api-key).


    ## Versioning


    Endpoints are versioned by path prefix (`/v3/`). Every response under

    a versioned prefix includes `X-API-Version`.

        `document_packet_id` is the dataset copy's id, as `by_document_packet`
        in

        `GET …/evals/{eval_id}/accuracy/` returns it, not the id of the

        packet the document was added from. The extracted values are the ones
        the eval

        graded. A document outside the eval, an unknown eval, or one on another

        workflow or organization returns 404.
