-### 4. REST API (`src/rest.rs`)
-
-**Responsibility**: HTTP interface for executing ggsql queries.
-
-**Technology**: Axum web framework with CORS support
-
-**Endpoints**:
-
-```rust
-// POST /api/v1/query - Execute ggsql query
-// Request:
-{
-  "query": "SELECT ... VISUALISE ...",
-  "reader": "duckdb://memory",  // optional, default
-  "writer": "vegalite"            // optional, default
-}
-
-// Response (success):
-{
-  "status": "success",
-  "data": {
-    "spec": { /* Vega-Lite JSON */ },
-    "metadata": {
-      "rows": 100,
-      "columns": ["date", "revenue", "region", "..."],
-      "global_mapping": "Mappings",
-      "layers": 2
-    }
-  }
-}
-
-// Response (error):
-{
-  "status": "error",
-  "error": {
-    "type": "ParseError",
-    "message": "..."
-  }
-}
-```
-
-**Additional Endpoints**:
-
-- `GET /` - Root endpoint (returns API information and status)
-- `POST /api/v1/parse` - Parse query and return AST (debugging)
-- `GET /api/v1/health` - Health check
-- `GET /api/v1/version` - Version info
-
-**CORS Configuration**: Allows cross-origin requests for web frontends
-
-**CLI Options**:
-
-```bash
-# Basic usage
-ggsql-rest --host 127.0.0.1 --port 3334
-
-# With sample data (pre-loaded products, sales, employees tables)
-ggsql-rest --load-sample-data
-
-# Load custom data files (CSV, Parquet, JSON)
-ggsql-rest --load-data data.csv --load-data other.parquet
-
-# Configure CORS origins
-ggsql-rest --cors-origin "http://localhost:5173,http://localhost:3000"
-```
-
-**Sample Data Loading**:
-
-- `--load-sample-data`: Loads built-in sample data (products, sales, employees)
-- `--load-data <file>`: Loads data from CSV, Parquet, or JSON files into in-memory database
-- Multiple `--load-data` flags can be used to load multiple files
-- Pre-loaded data persists for the lifetime of the server session
