Measured tools (7)

• list_zones read-only

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

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• get_prices read-only

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

  Parameters:

  • zone (required) — string — Bidding zone code, e.g. 'DE-LU'
  • to — string — ISO 8601 end (default: tomorrow)
  • from — string — ISO 8601 start (default: yesterday)
  • resolution — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• get_realtime_prices read-only

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

  Parameters:

  • zone (required) — string — Market reference code, e.g. 'US-WEIM-AZPS'
  • to — string — ISO 8601 end (default: now)
  • from — string — ISO 8601 start (default: last 24h)
  • market — string — Optional market filter, e.g. 'weim'

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• get_forecast read-only

  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.

  Parameters:

  • zone (required) — string
  • horizon — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• get_carbon read-only

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

  Parameters:

  • zone (required) — string
  • to — string
  • from — string

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• get_renewables read-only

  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.

  Parameters:

  • zone (required) — string — Bidding zone code, e.g. 'DE-LU'
  • to — string — ISO 8601 end
  • from — string — ISO 8601 start

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes

• cheapest_window read-only

  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.

  Parameters:

  • zone (required) — string
  • duration_minutes (required) — integer — Window length in minutes
  • to — string
  • from — string
  • count — integer — How many windows (default 3)
  • tariff — object — Optional variable household bill inputs; fixed monthly charges are excluded.
  • objective — string — Ranking objective (default cost). Carbon/balanced are experimental historical-profile heuristics, not forward carbon forecasts.

  Hints: read-only yes · destructive no · idempotent not declared · open-world yes
