> Monitor real-time water conditions across 562+ Czech river stations by accessing live water levels, flow rates, temperatures, and flood alerts. Search and track specific stations to get detailed hydrological data and historical time series information from the Czech Hydrometeorological Institute.

**Category:** Weather | **Website:** [hydro.chmi.cz/](https://hydro.chmi.cz/) | **Docs:** [parse.bot/marketplace/91c6945e-e62e-4b8a-ac9c-67b344003aea/hydro-chmi-cz-api](https://parse.bot/marketplace/91c6945e-e62e-4b8a-ac9c-67b344003aea/hydro-chmi-cz-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/hydro-chmi/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## 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/credits/hydro-chmi/get-station-detail \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -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/credits/hydro-chmi/get-stations \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -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/credits/hydro-chmi/search-stations \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"query":"<string>"}'
```
