compare-tariffs | 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 gene params: energyType, postalCode*, annualConsumptionKwh*, district, currentAnnualCostEur, currentMonthlyPaymentEur, currentWorkingPriceCtKwh, currentBasePriceEurMonth, currentProvider, currentTariff, sortBy, bonusMode, greenOnly, includeDynamicTariffs, contractMonthsMax, priceGuaranteeMonthsMin, cancellationMax, providers, maxTariffsPerProvider, includePrepayment, includeDeposit, includePackageTariffs, regionalOnly, goodRatingOnly, limit, page, language |
tariff-details | Returns the full conditions of one tariff from a compare-tariffs result, identified by its `ref`: price composition, scope of the price guarantee, contract duration, renewal and cancellation terms, deposit, energy-source mix, customer ratings, and for eco tariffs the required eco statement and proof. Texts come in the requested `language`. Keywords: Tarifdetails, Vertragsbedingungen, Preisgarantie params: language, ref* |
start-booking | Opens the booking form for one offer from a comparison, identified by its `ref`; the form renders below the message. Read-only: the call submits, stores and sends nothing, and takes no personal data. In the form the user enters the contract details (page 1), then the IBAN and consent (page 2), and files the request there. Messages such as 'Bitte öffne das Buchungsformular', 'ich möchte diesen Tari params: ref*, language |
compare-mobile-plans | Compares and ranks US mobile phone plans, cheapest first, from a curated catalog of carrier and prepaid (MVNO) plans, each price checked on the provider's own page, by 12-month average cost per line, with any promo price shown alongside. The catalog is a selection, not the whole market; each result states how many plans and providers it covers and the oldest price-check date. Inputs: number of lin params: lines, data_need, budget_per_line, prepaid_or_postpaid, must_haves, preferred_network |

compare-esims | Use this when the user needs phone data abroad: a travel eSIM, an international data plan for a trip, avoiding roaming charges, "will my phone work in Japan", the cheapest data for N days in a country, or unlimited travel data.

book-contract | Files a concierge switch request with the complete contract data in one call. Intended for autonomous agents that already hold the user's full profile, IBAN and a standing authorization; in a conversation with a person, start-booking opens a form in which the user enters these data. Commerce for Agents stores the request encrypted and an operator submits the contract application to the provider; t params: ref*, language, salutation*, firstName*, lastName*, birthDate*, email*, phone, street*, houseNumber*, switchType*, previousProvider, moveInDate, previousCustomerNumber, meterNumber, desiredStartDate, iban*, accountHolder, consent* |
submit-switch-request | Files a concierge switch request for an offer from a comparison: contract data, IBAN and the consents in one call. The booking form opened by start-booking calls it; autonomous MCP clients that hold the user's complete data and authorization can call it directly. Stores the request encrypted, sends the confirmation emails and returns only masked data. An operator later submits the contract applica params: ref*, language, salutation*, firstName*, lastName*, birthDate*, email*, phone, street*, houseNumber*, switchType*, previousProvider, moveInDate, previousCustomerNumber, meterNumber, desiredStartDate, accountHolder, iban*, authorization*, idempotencyKey* |

Returns FCC availability and maximum advertised speeds params: address, lat, lon, minDownloadMbps, technology |
