# Stream Workflow Status API

REST API for accessing stream workflow status and commit data.

## Server Configuration

The API server is configured via environment variables:

```bash
API_ENABLED=true    # Enable/disable API server
API_PORT=3001       # Port to listen on (default: 3001)
```

## Starting the Server

The API server starts automatically when the MCP server starts if `API_ENABLED=true`:

```bash
# Start the server
pnpm build
node dist/server.js

# Or for development
pnpm dev
```

Server will be available at: `http://localhost:3001`

## CORS

CORS is enabled for all origins in development. Configure appropriately for production.

---

## Dashboard

The API server also serves the React dashboard as static files:

```
http://localhost:3001/
```

All non-API routes fall back to serving the dashboard SPA (Single Page Application).

---

## Testing

Test the API using the provided test script:

```bash
./test-api.sh
```

Or manually with curl:

```bash
# Health check via stats
curl http://localhost:3001/api/stats | jq '.'

# List all streams
curl http://localhost:3001/api/streams | jq '.streams | length'

# Get recent commits
curl http://localhost:3001/api/commits?limit=10 | jq '.commits[0]'
```
