# TRACE disk-scoped actor instance path

Source: https://docs.wabe.sh/api-reference/operations/fetchactorondisktracepath/

`TRACE https://api.wabe.sh/v1/actor/{name}/disks/{disk}/instances/{instance}/fetch/{rest}`

The project key authorizes the call and selects the namespace. Wabe creates the named disk if needed and consumes the project key before forwarding the request. See the [actor transport protocol](https://docs.wabe.sh/cloud/actor-protocol/).

## Request example

```sh
curl --fail-with-body --request TRACE 'https://api.wabe.sh/v1/actor/chat/disks/demo/instances/room-1/fetch/messages' \
  -H 'Authorization: Bearer YOUR_PROJECT_API_KEY'
```

## Authorization

Project API key from the Wabe Dashboard.

## Parameters

- `name` (path, string, required) — Registration name in the current project.

- `disk` (path, string, required) — Disk name in the current project.

- `instance` (path, string, required) — Instance name on the selected actor and disk.

- `rest` (path, string, required) — Path suffix. Encode each component and preserve slash separators.

## Responses

### default

Handler status, headers and body, or a broker error.
