# StateSet UCP Quickstart

This quickstart helps you run the UCP handler locally and verify the discovery endpoint.

## 1) Run the server

```bash theme={null}
git clone https://github.com/stateset/stateset-ucp-handler.git
cd stateset-ucp-handler
```

```bash theme={null}
cd stateset-ucp-handler
cargo run
```

By default the server listens on `http://0.0.0.0:8081`.

## 2) Verify discovery

UCP exposes discovery at `/.well-known/ucp`:

```bash theme={null}
curl http://localhost:8081/.well-known/ucp
```

## 3) Create a checkout session

Refer to the handler README for full request/response examples and optional extensions:
