## Parsing SDMX-JSON Responses

The response structure nests data under `data.dataSets[0].series`. Each series key like `"0:0:0:0"` maps to dimension values in `data.structure.dimensions.series`. Observations are in `observations` keyed by time index.

```python
import json

data = json.loads(response_text)
series = data["data"]["dataSets"][0]["series"]
time_periods = data["data"]["structure"]["dimensions"]["observation"][0]["values"]

for series_key, series_data in series.items():
    for time_idx, obs in series_data["observations"].items():
        period = time_periods[int(time_idx)]["id"]
        value = obs[0]
        print(f"{period}: {value}")
```

## Key Policy Rate (Styringsrenten)

curl -s "https://data.norges-bank.no/api/data/KPRA/B.KPRA?format=sdmx-json&lastNObservations=5"

```bash
curl -s "https://data.norges-bank.no/api/data/NOWA/B.NOWA.RATE+VOLUME+TRADECOUNT?format=sdmx-json&lastNObservations=5"
