# Sandbox Files API Overview

> Read, write, delete, and list files through the sandbox proxy.

The sandbox file API is exposed through each sandbox's management hostname, not `https://api.tensorlake.ai`.

```text theme={null}
https://<sandbox-id-or-name>.sandbox.tensorlake.ai
```

Use these endpoints to read files, upload content, delete files, and list directory contents inside a sandbox.

<Note>
  Include `Authorization: Bearer $TENSORLAKE_API_KEY` on requests to the sandbox proxy.
