| :--- | :------------------------------------- |
| 400  | Invalid request                        |

Resource lists use cursor-based pagination. Standard parameters:

-   `page[size]` — number of items per page (default: 20, max: 100)
-   `page[after]` — cursor for the next page (value of the `meta.next` field)

Example:

```text
GET /v1/transport/orders?page[size]=50&page[after]=eyJpZCI6MTIzfQ==
```

Any backward-incompatible change is published as a new major version. Previous versions remain active until the end of the transition period, communicated in advance via the portal.
