# DStack Tappd RPC API Documentation (Legacy)
2+
3+
This document describes the legacy REST API endpoints for the DStack Tappd service. These APIs are deprecated as of version 0.4.2. For newer versions, please refer to [api.md](api.md) which contains the current API documentation.
4+
5+
## Base URL
6+
7+
The DStack Tappd service listens on a Unix domain socket at `/var/run/tappd.sock`. All API requests should be made to this socket using the `--unix-socket` flag with curl.
8+
9+
Make sure to map the Unix socket in your Docker Compose file:
10+
11+
```yaml
12+
services:
13+
jupyter:
14+
image: quay.io/jupyter/base-notebook
15+
volumes:
16+
- /var/run/tappd.sock:/var/run/tappd.sock
17+
```
18+
19+
