# New Features

CRCLA V2.0 introduces several improvements designed to make the API faster and more scalable.

## Key Highlights

* **Improved Performance:** Endpoints now return lighter responses by moving large related datasets to paginated URLs.
* **Versioning:** All v2.0 endpoints are available under the `/api/v2/` namespace.
* **Hyperlinked Relationships:** Instead of embedding large nested arrays, related records are now referenced by hyperlinks you can query separately.

***

## Changes to Related Endpoints

To speed up queries and improve response times, three fields that previously returned all records inline have been updated to provide paginated URLs instead.

| Field                | Type         | Documentation Link                                                                            |
| -------------------- | ------------ | --------------------------------------------------------------------------------------------- |
| `case_documents_url` | string (URL) | [#case\_documents\_url](/api-reference-v2/objects/case/pagination-urls.md#case_documents_url) |
| `case_dockets_url`   | string (URL) | [#case\_dockets\_url](/api-reference-v2/objects/case/pagination-urls.md#case_dockets_url)     |
| `case_resources_url` | string (URL) | [#case\_resources\_url](/api-reference-v2/objects/case/pagination-urls.md#case_resources_url) |

These fields now return a link you can follow to retrieve related records in a paginated format.

To learn more about pagination behavior, see [Pagination](/api-reference-v2/new-features/pagination.md).

### Removed Fields

As part of this change, a few fields that previously contained large serialized data has been removed and replaced by the URL fields listed above:

* `case_documents`
* `case_dockets`
* `case_resources`

If your integration relied on these fields, you will now need to follow the corresponding URL to retrieve related records.

***

### Query Related Records Directly

In addition to using the `*_url` fields returned in each `Case` object, you can also **query related records directly by filtering on the `case` parameter**.

This allows you to retrieve all related resources for a case without relying only on hyperlinks.

#### Examples

* Retrieve all resources for a specific case: `/api/v2/resources/?case=15150`
* Retrieve all documents for a specific case: `/api/v2/documents/?case=15150`
* Retrieve all dockets for a specific case: `/api/v2/dockets/?case=15150`

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://api.clearinghouse.net/api-reference-v2/new-features.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
