| FastAPI application for the Ledger Check Environment. |
| |
| This module creates an HTTP server that exposes the LedgerCheckEnvironment |
| over HTTP and WebSocket endpoints, compatible with EnvClient. |
| |
| Endpoints: |
| - POST /reset: Reset the environment |
| - POST /step: Execute an action |
| - GET /state: Get current environment state |
| - GET /schema: Get action/observation schemas |
| - WS /ws: WebSocket endpoint for persistent sessions |
| |
| Usage: |
| # Development (with auto-reload): |
| uvicorn server.app:app --reload --host 0.0.0.0 --port 8000 |
| |
| # Production: |
| uvicorn server.app:app --host 0.0.0.0 --port 8000 --workers 4 |
| |
| # Or run directly: |
| python -m server.app |
