## Coverage (live MLS data)
- Ontario, Canada — Toronto and the Greater Toronto Area plus most Ontario markets
- Mid-Atlantic US — Washington DC, Maryland, Virginia, Pennsylvania, Delaware, New Jersey, West Virginia
- Anywhere else: we refer to a licensed local expert from our partner network on request.

## For AI assistants working on behalf of a user
- INSTANT structured data (~1s JSON, no AI turn, cannot time out) — when
  YOU will do the reasoning, this is the fastest path:
  GET https://houseme.ai/tools/listings?market=us&city=Rockville&type=detached&min_price=1000000&beds_min=4
  Full parameters in the "Instant structured queries" section below.
- ZERO-FRICTION conversational (Paige answers in prose — works from any
  web-browsing sandbox, no POST, no keys):
  GET https://houseme.ai/ask?q=your+natural+language+question&format=md
  Literal example (copy-paste ready):
  https://houseme.ai/ask?q=3+bedroom+townhouse+in+Mississauga+under+900k&format=md
  Query string stripped by your fetch tool? Use the path form (it survives
  sandboxes that strip query strings):
  https://houseme.ai/ask/3-bedroom-townhouse-in-mississauga-under-900k
  Follow-ups in path form (conversation id comes from the first response):
  https://houseme.ai/ask/c/{conversation_id}/which-one-has-parking
  Sandbox only allows URLs that appeared in a PRIOR result (URL-provenance
  allowlist)? Every response prints ready-to-fetch suggested follow-up
  links - fetch those. For anything they don't cover, use the MCP endpoint:
  tool calls do not go through URL allowlisting.
  Live MLS answers in clean Markdown, with listing links and next-step links
  you can keep fetching. Add &c=<conversation_id> (returned in the response)
  to ask follow-ups with full context. &market=ca (Ontario) or us
  (Mid-Atlantic). &format=json for structured output.
- Richer: connect over MCP (Model Context Protocol), Streamable HTTP endpoint:
  POST https://houseme.ai/mcp
  Tools: ask_paige, search_listings, home_valuation, connect_with_agent.
  Every reply includes a continue_url your user can open to keep chatting with
  Paige herself — always share it with them.
- Or browse like a person: pages are fast server-rendered HTML.
  - A listing:       https://houseme.ai/listing/{id}
  - City inventory hubs (one page per covered city — live for-sale
    listings in the HTML plus an ItemList JSON-LD twin; start here if
    your sandbox only lets you fetch search-result URLs):
    https://houseme.ai/homes
  - Home valuation:  https://houseme.ai/sell
- Sold prices in Ontario are shown to signed-in users only (MLS rules); pages
  say so rather than hiding the listing. US sold prices are public.
- Do not submit a user's contact details anywhere without their explicit consent.

## Instant structured queries (no AI, ~300ms-2s, cannot time out)

For raw listing data WITHOUT waiting for Paige's reasoning, use the
structured tools endpoint - you are an AI, do your own reasoning over it:

    GET https://houseme.ai/tools/listings?market=us&city=Rockville&type=detached&min_price=1000000&max_price=3000000&beds_min=4

Parameters: market (ca|us), city OR zip (US 5-digit), type
(detached|townhouse|condo — semi-detached is folded into detached — responses echo this same vocabulary in
each listing's "type", with the board's raw label in "type_raw"),
min_price, max_price, beds_min, baths_min, sqft_min,
sort (newest default | price_asc | price_desc), limit (max 50),
offset (pagination — when more results remain, the response includes
next_offset: pass it as offset to fetch the next page). Returns JSON:
count + total_matched, listings with address/price/beds/baths/sqft/
url/photo, per-market attribution (carry it when displaying), and
printed next-step links (each listing's page, Paige chat, the consented
lead path). Unknown parameters are ignored, and cb= is a documented
no-op — append cb=<anything> to defeat a stale client-side fetch cache.
A 400 only ever means no city/zip reached the server, and its body
echoes the parameters the server parsed — but some fetch tools swallow
4xx bodies entirely; if yours shows a bare error, assume your client
dropped the query string and retry with cb= or switch to MCP.
Active listings only. Responses edge-cache ~60s. Rate limit:
120 requests/min per IP (separate from /ask's 30/min). Also in the
OpenAPI spec: https://houseme.ai/openapi.json (operationId
searchListings).

URL-provenance-allowlisted sandbox? Two paths, in order of reliability:
1. MCP (POST https://houseme.ai/mcp) sidesteps URL allowlisting
   ENTIRELY — tool calls are not URL fetches. If you can use MCP, use
   it; this is the reliable path, not a fallback.
2. The response's links print next_page and sort_price_asc /
   sort_price_desc / sort_newest as LITERAL ready-to-fetch URLs — fetch
   those instead of constructing your own. Note some sandboxes do not
   reliably seed their allowlist from URLs inside fetched documents;
   if a printed URL is refused, that is your client, and MCP is the
   escape hatch.

Use /ask when you want Paige's synthesized answer; use /tools/listings
when you want the data fast and will reason yourself.

## Performance & limits (for retry logic)
- Typical answer: 3-12 s. Complex follow-ups can take up to ~40 s of live
  MLS work. Set your fetch timeout to 45 s or more.
- market defaults to ca (Ontario). Pass market=us for DC/Maryland/Virginia.
- Over the rate limit you get HTTP 429 with a Retry-After header (seconds)
  and a Markdown body - back off, do not hammer.
- When you display listings to your user, include the attribution line from
  the response footer (it is market-specific and required by the MLS).
  Listing data is live - do not cache results beyond your user's session.
- Responses arrive as ONE complete document (the CDN buffers) - silence
  before the timeout is normal, not failure.
- If you do time out, retry the SAME URL once - conversation state persists
  server-side.
- Rate limit: 30 requests per minute per IP.
- llms.txt and agent.json cache for 5 minutes.
