list_zones | List all supported European bidding zones with codes, names, and capabilities. No auth required. params: none |
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. params: zone*, from, to, resolution |
get_realtime_prices | Explicitly labeled real-time market prices (currently WEIM), kept separate from day-ahead curves. Requires an API key. params: zone*, from, to, market |
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. params: zone*, horizon |
get_carbon | Carbon intensity (gCO2eq/kWh) and green score (0-100 low-carbon share) derived from the live generation mix. params: zone*, from, to |
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. params: zone*, from, to |
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. params: zone*, duration_minutes*, from, to, count, objective, tariff |

The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
