- **GET**: Returns metadata (table structure, dimension codes, labels)
- **POST**: Returns data in JSON-stat2 format
## Endpoint Reference
### Health Check
- **GET** `/healthz` - Returns 200 OK if service is running
### Species Lookup
- **GET** `/api/species` - Returns list of all species codes and Faroese names
### Zones Lookup
- **GET** `/api/zones` - Returns list of all economic zone codes and labels
### Gear Lookup
- **GET** `/api/gear` - Returns list of all fishing gear codes and labels
### Landings Data
- **GET** `/api/landings` - Returns filtered landing records
**Query Parameters:**
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `month` | string | No | Single month filter (legacy, e.g., `2024M01`) |
| `month_from` | string | No | Start of date range (inclusive, e.g., `2024M01`) |
| `month_to` | string | No | End of date range (inclusive, e.g., `2024M12`) |
| `species` | string | No | Filter by species code (e.g., `COD`) |
| `gear` | string | No | Filter by gear code (e.g., `TR1`) |
| `zone` | string | No | Filter by zone code (e.g., `FO`) |
| `measure` | string | No | Filter by measure type (`MASS` or `VALUE`) |
| `limit` | integer | No | Max results (default: 10000, max: 10000) |
**Example:**
bash curl "http://localhost:8090/api/landings?month_from=2024M01&month_to=2024M06&species=COD&limit=1000"
### Summary Aggregates
- **GET** `/api/summary` - Returns aggregated statistics
**Query Parameters:**
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `species` | string | No | Filter aggregations by species code |
**Response Fields:**
- `monthly`: Array of `{month, total_mass, total_value}`
- `top_species`: Array of top 10 species by value
- `price_trend`: Array of `{month, price_per_kg}`
### Parquet Export
- **GET** `/api/export.parquet` - Downloads full dataset as Parquet file
**Note:** Triggers temp file creation in system temp directory with automatic cleanup after 300 seconds.

Summary of Changes
File Change Reason
src/api.rs Added MAX_LIMIT constant and hard cap Prevent unlimited query results
src/api.rs Replaced CorsLayer::permissive() with explicit origins Security hardening
src/api.rs Updated tempfile::Builder with prefix Ensure cleanup function finds files
src/api.rs Added test_get_landings_range_filter test Cover new range-filtering logic
src/types.rs Added allowed_origins field to Config Support CORS configuration
