A3.7/5.0

Scored across 7 tools

Disambiguation4/5

Each tool targets a distinct data area: zones, day-ahead prices, real-time prices, forecasts, carbon, renewables, and action optimization. get_prices and get_realtime_prices are adjacent but explicitly separated by market timing, so ambiguity is low. get_forecast and get_prices could be confused at a glance, but their descriptions clarify forecast vs. actual prices.

Naming Consistency4/5

Six of seven tools follow a clear get_* pattern, with list_zones as a standard list verb. cheapest_window breaks the verb_noun convention, though its name is still descriptive. The set is mostly consistent with minor deviations.

Tool Count5/5

Seven tools is well-scoped for a market data API covering zones, prices, forecasts, carbon, renewables, and optimization. Each tool earns its place without redundancy or bloat.

Completeness4/5

The surface covers the core lifecycle of market data discovery: zone enumeration, price retrieval (day-ahead and real-time), forecasting, carbon insight, and renewables. Missing historical data or account management tools are minor gaps that agents can work around, as the focus is clearly on current and forward-looking data.

Available Tools

7 tools
cheapest_windowCheapest WindowA
Read-only
Inspect

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.

Inputs: zone (required), duration_minutes (required), to, from, +3 more.

get_carbonGet CarbonC
Read-only
Inspect

Carbon intensity (gCO2eq/kWh) and green score (0-100 low-carbon share) derived from the live generation mix.

Inputs: zone (required), to, from.

get_forecastGet ForecastA
Read-only
Inspect

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.

Inputs: zone (required), horizon.

get_pricesGet PricesA
Read-only
Inspect

Day-ahead electricity prices in each zone's native currency and native market resolution. Connect an existing Voltcast account to access account-scoped data.

Inputs: zone (required), to, from, resolution.

get_realtime_pricesGet Realtime PricesA
Read-only
Inspect

Explicitly labeled real-time market prices (currently WEIM), kept separate from day-ahead curves. Requires an API key.

Inputs: zone (required), to, from, market.

get_renewablesGet RenewablesA
Read-only
Inspect

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.

Inputs: zone (required), to, from.

list_zonesList ZonesA
Read-only
Inspect

List all supported European bidding zones with codes, names, and capabilities. No auth required.

Inputs: no named parameters.
