Compares German electricity and gas tariffs with live market data for a postal code and an annual consumption, and returns one page of the ranked market: prices with and without bonus, monthly average, savings against the local default supplier (Grundversorgung) or the user's current contract, contract terms, price guarantee, eco status and customer ratings. Covers tariff comparison only, not general energy questions. Prices come live from the market data and can change at any time. Keywords: Stromvergleich, Gasvergleich, Stromtarif, Gastarif, Stromanbieter wechseln, Gasanbieter wechseln, Ökostrom, Strompreise, Energiekosten senken, electricity tariff, gas tariff, switch energy provider, Germany. Inputs: postalCode (5 digits) and annualConsumptionKwh. Both come from the user: the ranking is only valid for the household's actual consumption, which is printed on the last bill, and the tool has no default for it. The typical values by household size in the parameter description help a user who does not know the figure; a comparison run on a household size alone is approximate. energyType selects gas; electricity is the default. Without filters the result covers the whole market. An energy bill contains every input: postal code, annual consumption, and the reference for the savings comparison, which is the future monthly payment (Abschlag) if the bill states one, otherwise the Arbeitspreis and Grundpreis lines (see the current* parameters). The bill total belongs to the past period and may include a one-time bonus, so it is not a reference. The bill's provider, customer number and meter number are the fields the booking form asks for later. Each offer carries its complete data (prices, bonuses, contract terms, flags such as dynamic or eco, ratings, remarks); tariff-details adds the cost breakdown, energy mix and provider details. Only offers with an `eco` object are eco tariffs. Their `eco.statement` and `eco.proof` are legally required wording (EU EmpCo, Directive 2024/825): quote both verbatim when describing a green tariff. Offers without `eco` are not green, eco, renewable or climate-neutral. The ranking method, bonus handling, price guarantees and eco labels are explained at https://commerceforagents.com/comparison-basis. The response states totalResults and how to reach the rest of the ranking (page, providers, filters). Dynamic (spot-price) tariffs are included only with includeDynamicTariffs. The result renders as tariff cards with filters (eco, contract length, price guarantee, bonus handling, providers) below the message, so the list does not need repeating in text. Each offer has a `ref`: tariff-details shows its full conditions, and start-booking opens the booking form in which the user enters the contract data, IBAN and consent. `language` sets the language of the cards and their buttons.
