Capabilities

Tools 7

compare_grocery_prices

For one product id from a Schnäppchen Jäger search, returns its price, the identical article in the other Swiss shops (matched by barcode) and the cheapest similar product per shop for the same amount, each with the date it was read and a link. Similar products are not the same article. By zzd (schnaeppchenjaeger.zzd.ch). Not counted against the search allowance.

Discovered
ev_cost_per_km

Electric cars offered in Switzerland ranked by total cost in CHF per km (depreciation, capital, tax, insurance, tyres and service, energy, wallbox, import fees, monthly fees), across buying new or used, importing from Germany, leasing and subscriptions, from the EV cost comparison (ev.zzd.ch, free, by zzd). Optional driving profile. The offers are a dated, hand-collected snapshot, not live prices; the model is calibrated for canton Aargau. The result links the comparison page.

Discovered
find_map_posters

Find the ready poster page for a town or place on MappaMuse (mappamuse.zzd.ch, personalised map posters printed to order, by zzd), with the sizes and prices that page lists, in CHF. Any other place can be designed on the custom-poster page. The result links the page; the page and checkout are binding.

Discovered
find_wedding_venues

Find places for a civil wedding in Switzerland as cantons and municipalities publish them (registry offices and outside venues such as castles), from Trauungslokale Schweiz (traulokale.zzd.ch, a free finder by zzd). Filter by canton (code, slug or name), town, text, guests, or a published ceremony date or date range. Important: most offices publish no dates; and where datesShowAvailability is false a published date is NOT known to be free. The date is always booked with the registry office. Each venue links its page.

Discovered
get_wedding_venue

Details for one venue id from a venue search: address, guests, costs as published, all published dates, the responsible registry office with phone, e-mail and official page, and the source the data was read from. By zzd (traulokale.zzd.ch).

Discovered
rent_reference

The usual net monthly rent by flat size in a Swiss canton, from the Federal Statistical Office (BFS), via Mietcheck (mietcheck.zzd.ch, free, by zzd). Give a canton or a place (postal code or municipality); with rooms and the net rent it also says whether that rent is below, within or above the usual range. A place in several cantons returns the candidates to choose from. Cantonal averages only: not street level, not legal advice. The result links the matching Mietcheck page.

Discovered
search_grocery_prices

Search the grocery catalogue of Schnäppchen Jäger (schnaeppchenjaeger.zzd.ch, a free Swiss price comparison by zzd) across Migros, Coop, Lidl, Aldi, Denner and Volg, plus Aligro's weekly promotions. Returns products with pack price, price per unit, offer flag, the date each price was read, and a link to each product's comparison page. Prices are the shops' online prices, not branch shelf prices. Counts as one search of the site's free daily allowance (5 a day per connection without an account; calls through Claude's connectors share 300 a day). Each product links its comparison page.
