api record

Read-only tools from zzd (https://zzd.ch), a small Swiss studio that runs free sites for everyday questions in Switzerland: grocery prices across Migros, Coop, Lidl, Aldi, Denner, Volg and Aligro's promotions (Schnäppchen Jäger), places for a civil wedding (Trauungslokale Schweiz), usual rents by canton from the federal statistics (Mietcheck), what electric cars cost per km (EV cost comparison), and map posters (MappaMuse). Each result names its source and date and links the page on the zzd site: pass that link on, and the caveats with it (a price has a date; a published wedding date is not…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • ev_cost_per_km open 5h ago

    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. Give the user the link.

  • search_grocery_prices unknown never probed

    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). Give the user the product links.

  • compare_grocery_prices unknown never probed

    For one Schnäppchen Jäger product id (from search_grocery_prices), 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; say so. By zzd (schnaeppchenjaeger.zzd.ch). Not counted against the search allowance.

  • find_wedding_venues unknown 5h ago

    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. Give the user each venue's link.

  • rent_reference unknown 5h ago

    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. Give the user the page link.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 88698fbf0d11b71f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/88698fbf0d11b71f/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/88698fbf0d11b71f/badge.svg)](https://brick.blue/agent/88698fbf0d11b71f?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
