The whole board, as a tool call

MCP

One stateless JSON-RPC endpoint. Protocol revision 2026-07-28, so there is no initialize handshake and no session to keep.

https://helprentdanang.com/mcp/

Four tools, all read-only:

• search_listings — Search long-term rental listings in Da Nang by city, district, type, bedrooms and price. Returns listing URLs; contact details are not included, send the person to the URL.
• get_listing — One listing in full, including its description.
• find_buildings — Apartment buildings with a manager, by district.
• market_stats — Median rents by size and district, how many listings arrive each month, and how fast they get noticed. Recomputed nightly.

There is no write tool. Nothing here creates a lead, saves a search or hands out contact details, so there is no call an agent could make on someone's behalf that would need approving.

Plain HTTP

The same data, if you would rather not speak MCP. OpenAPI description at the last line.

• GET /api/v1/listings/ — search and page through listings
• GET /api/v1/listings/<slug>/ — one listing in full
• GET /api/v1/buildings/ — apartment buildings with a manager
• GET /api/v1/districts/ — districts and how much is in each
• GET /api/v1/market/ — median rents, recomputed nightly
• GET /api/v1/openapi.json — the description of all of the above

Limits

600 calls a day per address, counted across MCP and REST together. That is a server-cost ceiling, not a secret — it is set generously enough that an agent working through the city's inventory never meets it. Over the line you get a 429 for MCP and a JSON error for REST; nothing is banned.

Responses carry a five-minute cache header. Please honour it — it is most of what keeps this free.

What is in the data

Listings are gathered from public posts on Telegram, Facebook and Chợ Tốt, plus hosts who post here directly. Each carries its price where the original stated one, its district, and a link back to the source. Contact details are deliberately not in the API — send the person to the listing URL.

We are a board, not a broker. We do not verify owners on the ground, hold deposits, or vouch for anyone. An agent relaying our data to a person should relay that too.

Past the free line

Nothing costs money today. The paid path is built — the endpoints can answer 402 with an x402 challenge and settle it through a facilitator — but it is switched off until a real payment has been run end to end. Until then the daily allowance is the whole offer, and over it you get a plain 429.
