## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/parse-hydro-chmi-cz-api-91c6945e/`
**Auth:** `Authorization: Bearer <LOCUS_API_KEY>`

## Endpoints

### get_station_detail

Get detailed station data including metadata, measured data table (datetime, water height, flow rate, temperature), SPA flood alert levels, and graph time series. Temperature data availability varies by station. Forecast data is included only for category A stations when available.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `station_id` | string | Yes | Station sequence ID. Get IDs from the get_stations endpoint (e.g., '307053', '307076'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-hydro-chmi-cz-api-91c6945e/get_station_detail \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"station_id":"<string>"}'
```

### get_stations

List monitoring stations with their current measurements. Returns station metadata, current water level, flow rate, status, and tendency. Supports pagination (50 per page) or retrieving all stations at once. Pagination via integer page numbers (1-12); 'all' returns the full station list in one call.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | string | No | Page number (1-12) or 'all' for all stations. Each page has ~50 stations. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-hydro-chmi-cz-api-91c6945e/get_stations \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"page":"<string>"}'
```

### search_stations

Search monitoring stations by name, river, or region. Performs case-insensitive substring matching across station names, river names, and region names. Fetches all stations and filters locally, so results reflect the full network.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search query to match against station name, river name, or region (e.g., 'Labe', 'Praha', 'Vltava') |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/parse-hydro-chmi-cz-api-91c6945e/search_stations \
  -H "Authorization: Bearer YOUR_LOCUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query":"<string>"}'
