Simulate the cost of a product version (full or partial year)

Returns the estimated cost of the given product version for the supplied consumption profile — a cost breakdown of energy cost, injection fee, and discounts. Defaults to a full year; pass yearFraction (in (0, 1]) to price a partial year — e.g. a mid-year supplier switch. yearFraction pro-rates only the time-based fixed/recurring fees (the energy-cost fixed fee / standing charge, the regulated fixed network fees, and the energy-fund excise); per-kWh charges (energy usage, WKK / green certificates, per-kWh excise and distribution, injection) follow the consumption figures you provide, so supply consumption for the period being simulated. The supplied (postalCode, city) must resolve to a Distribution Network Operator Vwala can price; call GET /v1/serviceable-locations to discover valid postal codes/cities and which energy types each supports. See the 422 response for the location and validation errors this can return.
