## Tools (as reported by the server, not verified)

- `list\_zones`: List all supported European bidding zones with codes, names, and capabilities. No auth required.
- `get\_prices`: Day-ahead electricity prices in each zone's native currency and native market resolution. Connect an existing Voltcast account to access account-scoped data.
- `get\_realtime\_prices`: Explicitly labeled real-time market prices \(currently WEIM\), kept separate from day-ahead curves. Requires an API key.
- `get\_forecast`: Probabilistic price forecast up to 7 days ahead. Returns the P50 curve and any uncertainty bands included in the connected account. Accuracy is published daily at voltcast.com/accuracy.
- `get\_carbon`: Carbon intensity \(gCO2eq/kWh\) and green score \(0-100 low-carbon share\) derived from the live generation mix.
- `get\_renewables`: Day-ahead wind and solar generation forecasts: the TSO official forecast and Voltcast model with uncertainty bands, realized generation, and disclosed head-to-head verification. Requires the corresponding existing account entitlement.
- `cheapest\_window`: Rank household action windows by cost using current Voltcast curves and optional user-supplied variable tariff inputs. Experimental carbon/balanced modes use a disclosed trailing historical production-mix profile—not a forward carbon forecast—and support no emissions-reduction claim.
