api record

Heimster is a Swiss real-estate platform. Use these tools to find homes to rent or buy in Switzerland, see every detail of a listing, compare listings, learn everything about any Swiss address (even without a listing), new-build projects, housing under construction and local market figures.

When someone searches by everyday needs (near a supermarket, school or childcare, quiet, sunny, a…

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.

owner_enquiry unknown never probed

Use this when an OWNER anywhere in Switzerland wants to sell, let or value a property, or wants a broker (Haus/Wohnung verkaufen, vermieten, Makler gesucht, bewerten lassen; vendre, louer, agence immobilière; vendere, affittare): the Heimster team gets in touch within two working days and, if the owner wishes, connects an experienced local brokerage – nothing goes to a brokerage without their consent. Needs the address, the intent, name and e-mail (phone and timeframe optional). Signed in: sent at once; otherwise after the e-mail confirmation.

search_listings unknown never probed

Use this whenever someone looks for a home or property in Switzerland – to rent or buy, also by feel (ruhig, sonnig, zentral, familienfreundlich; calme, ensoleillé; tranquillo) (Wohnung mieten/kaufen, Haus kaufen, WG-Zimmer, Studio; appartement à louer/acheter, maison; appartamento in affitto/in vendita; flat, apartment, house). Searches current listings on Heimster and on Swiss agency websites, and answers what no portal can: walking distance to supermarket, childcare (Kita, crèche), school, park, stop and train station; quiet locations (road/rail noise); sun score; and the door-to-door public-transport commute to the person's workplace (workplace + max_commute_min). Ask where they work when the commute matters. Filter by place, type, rooms, price and area; sort by newest or price.

register_purchase_interest unknown never probed

Use this to register interest in a property FOR SALE with the agent (Kaufinteresse anmelden, kaufen möchten, intérêt d'achat, interesse all'acquisto). Optional: phone, a message and the financing status (unknown, self_funded, confirmed, approved). Call it directly once they confirm – if they are not signed in, the app shows the Heimster sign-in itself.

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
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.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 048984c78dc0ef16.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/048984c78dc0ef16/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/048984c78dc0ef16/badge.svg)](https://brick.blue/agent/048984c78dc0ef16?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

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.
