Immoweb — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the immoweb-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install immoweb --cli-only

2. Verify: immoweb-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/other/immoweb/cmd/immoweb-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

Talks to the same JSON endpoints the immoweb.be website uses, with no login and no browser, and exposes every search filter as a flag. Everything you look at lands in a local SQLite history, so watch shows what is new, cheaper or gone since last time, deal judges one listing against its neighbours, and market rebuilds the commune price statistics Immoweb no longer publishes.

When to Use This CLI

Use this CLI for Belgian property searches on Immoweb: finding houses, apartments, land or rentals by commune and criteria, reading one listing's full details, tracking saved searches over time, and answering price questions (is this listing cheap, what did it cost before, what yield does a commune give) from the locally recorded history. It needs no Immoweb account.

Anti-triggers

Do not use this CLI for:

• Do not use it to contact agencies, book visits or post listings; those are Immoweb account or write actions it does not perform.
• Do not use it for property outside Belgium or for other portals such as Zimmo, Immovlan or Biddit auctions.
• Do not use it for official valuations, notary or registration-duty calculations; its figures are asking-price statistics, not appraisals.
• Do not use it to read the user's Immoweb favourites or account saved searches; it keeps its own local saved searches instead.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Market intelligence

• market — Median asking price, €/m², price-cut share and recent disappearances for one or several communes, broken down by bedrooms, EPC, type or postcode. Student rooms and per-room lets are left out. Pulls missing areas on first use (--no-pull to stay offline).

  Reach for this when an agent needs neighbourhood price levels or wants to compare communes before searching.

  immoweb-pp-cli market ixelles saint-gilles --type apartment --deal rent --by bedrooms --agent

• yield — Estimates gross rental yield for a sale listing or a whole commune from comparable rents, and refuses when there are too few comparables. Pulls missing areas on first use (--no-pull to stay offline).

  Use for investor questions about rental return before looking at individual listings.

  immoweb-pp-cli yield --commune liege --type apartment --agent

Decision support

• deal — Tells you whether one listing is cheap or expensive: €/m² percentile against comparable listings, days on market, price-cut history, demand and EPC gap. Pulls missing areas on first use (--no-pull to stay offline).

  Use before advising on an offer or deciding whether a specific listing is worth a visit.

  immoweb-pp-cli deal 21828249 --agent

• triage — Ranks the current matches of a saved search (or ad-hoc filters) by a transparent score: EUR/m2 percentile within the same postal code, freshness, price cut, private seller and EPC (with --enrich) so you know who to call first.

  Use when a search returns too many listings and the user needs a prioritised short list with reasons.

  immoweb-pp-cli triage --type apartment --deal rent --commune ixelles --max-price 1500 --min-bedrooms 2 --agent

Local state that compounds

• drops — Lists stored listings whose asking price fell (from prices recorded by find/watch/pull and Immoweb's old-price field), with first and latest price, number of cuts, total % cut and days listed.

  Use to find motivated sellers or negotiation leverage across everything the user has tracked.

  immoweb-pp-cli drops --commune liege --since 30d --agent

Discovery Signals

Command Reference

listings — Immoweb classifieds: search, count, map results, full details and similar listings

• immoweb-pp-cli listings count — Exact number of listings matching the filters (search pages cap at 9,969)
• immoweb-pp-cli listings get — Full details of one listing: EPC, cadastral income, surfaces, heating, agency contact, photos, views and bookmarks
• immoweb-pp-cli listings map — Up to 200 listings per call with GPS coordinates (the bulk path used by the Immoweb map view)
• immoweb-pp-cli listings search — Search listings with every Immoweb filter (30 per page, raw Immoweb result objects)
• immoweb-pp-cli listings similar — Listings Immoweb considers similar to a given listing

locations — Resolve commune names and postal codes to Immoweb location filters

• immoweb-pp-cli locations — Look up a commune, locality or postal code; returns the postalCodes value to pass to search filters

Search, track and analyse

• immoweb-pp-cli find - Live search with friendly filters (--type, --deal, --commune/--postcode/--province, price, bedrooms, surfaces, --epc, --garden...), --url to start from a pasted Immoweb search, --pages, --private-only, --hide-under-option, --near lat,lng --radius-km. Results are stored locally.
• immoweb-pp-cli show <id|url> - Readable listing card: price, EUR/m2, EPC, cadastral income, surfaces, days online, demand, agency contact, recorded price history.
• immoweb-pp-cli photos <id|url> - Download photos (--dir, --size small|medium|large|xl) or only list their URLs (--list).
• immoweb-pp-cli saved add|list|remove - Named local searches (same filters as find, or --url).
• immoweb-pp-cli watch <saved> / watch --all - New listings, price changes (with the old price) and listings gone since the last run. The first run records a silent baseline.
• immoweb-pp-cli pull - Harvest every listing of an area into the local store (--commune/--postcode, --type, --deal); splits the area into price bands of up to 200 listings so it needs only a few requests, and marks listings that disappeared as gone.
• immoweb-pp-cli hide <id...> (--undo) - Dismiss listings so find, watch and triage skip them.
• immoweb-pp-cli shortlist add|list|remove - Local shortlist with notes.
• immoweb-pp-cli dump - Export stored listings as --format csv|geojson|jsonl (a JSON array with --json).
• market, deal, triage, drops, yield - see Unique Features.

find, show, watch, pull and the automatic pulls of market/deal/yield/triage fill the local store; drops, dump, search and --no-pull runs read it. Do not use the generic sync command to fill the store: it has no area filter and would page through listings for all of Belgium. Use pull instead.

Known behaviours

• The 19 Brussels communes resolve to their own postal codes (Ixelles = 1050), because Immoweb's "(all localities)" grouping adds neighbouring codes (Ixelles would include 1000, the City of Brussels). Elsewhere a commune follows Immoweb's grouping: check it with immoweb-pp-cli locations --query <name>, and use --postcode or market --by postcode for a clean split.
• Student rooms (kots) and per-room lets are left out of market, yield and triage, and deal compares rooms only with rooms; --include-rooms keeps them.
• The first market, deal or yield on an area pulls it from Immoweb (a few seconds, up to ~20 s for large communes on a slow connection). The pull is reused for 24 h (--refresh-after); --no-pull or --data-source local stay offline.
• Days on market come from Immoweb's publication date, which only the listing detail carries: they appear after show, deal or triage --enrich. Without it, market leaves the median out and says why, and triage scores freshness on the last update date.
• Listings without a published price ("price on request") cannot be reached through price bands; pull reports them as without_price.
• Immoweb soft-throttles by returning empty pages; the CLI turns that into exit code 7 instead of an empty result. Wait a minute and retry.
• triage leaves out hidden listings and listings under option (--include-under-option keeps them).

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

immoweb-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query. --json (and other machine formats) keep that exit-2 contract and write {"matches":[]} on stdout so agents can inspect the envelope without treating a miss as success.

Recipes

Who to call first for a rental search

immoweb-pp-cli triage --type apartment --deal rent --commune ixelles --max-price 1500 --min-bedrooms 2 --agent

Ranks current matches with the per-factor breakdown (EUR/m2 vs the same postal code, freshness, cut, private seller); add --enrich 5 to score EPC for the top five.

Is this house fairly priced?

immoweb-pp-cli deal 21828249 --agent

Returns the €/m² percentile against comparables, days on market and any recorded price cuts.

Key facts from a listing, agent-sized

immoweb-pp-cli listings get 21828249 --agent --select classified.price.mainValue,classified.property.netHabitableSurface,classified.transaction.certificates.epcScore,classified.statistics.viewCount

The raw detail JSON is about 20 KB; --select keeps only the dotted fields the agent needs.

Compare commune rents

immoweb-pp-cli market ixelles saint-gilles etterbeek --type apartment --deal rent --by bedrooms --agent

Median rent and €/m² per bedroom count, side by side, with sample sizes.

Recent price cuts in what you have tracked

immoweb-pp-cli drops --since 30d --agent

Reads the local store only: cuts come from prices recorded by find, watch and pull plus Immoweb's own old-price field, so pull an area first (immoweb-pp-cli pull --commune liege --type apartment --deal sale).

Auth Setup

No authentication required.

Run immoweb-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color.

Global format flags share one contract on promoted, novel, sync, and --deliver paths:

• --json — one JSON document on stdout (sync progress events go to stderr)

• --compact — keep identity/status/timestamp fields; does not change the document vs stream shape

• --csv / --plain — tabular rows (collection envelopes unwrap to the row array)

• --quiet — one identity value per row, no envelope

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  immoweb-pp-cli listings get 21828249 --agent --select classified

• Previewable — --dry-run shows the request without sending

• Offline-friendly — drops, dump, search and --no-pull runs read the local SQLite store filled by find, show, watch and pull (never sync, which has no area filter)

• Non-interactive — never prompts, every input is a flag

• Read-only toward Immoweb — it never contacts agencies or changes anything on immoweb.be; its only writes are the local store (saved searches, hidden listings, shortlist) and downloaded photos

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local (for market/deal/yield, pass --data-source local rather than --no-pull when you need the envelope to say local). A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Paths and state

Agents should treat the CLI's path resolver as part of the runtime contract:

• Use --home <dir> for one invocation, or set IMMOWEB_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: IMMOWEB_CONFIG_DIR, IMMOWEB_DATA_DIR, IMMOWEB_STATE_DIR, IMMOWEB_CACHE_DIR.

• Resolution order is per-kind env var, --home, IMMOWEB_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.

• config contains settings like config.toml and profiles. data contains data.db (listings, price history, saved searches). state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.

• Run immoweb-pp-cli doctor --fail-on warn to surface path warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.

• For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:

  {
    "mcpServers": {
      "immoweb": {
        "command": "immoweb-pp-mcp",
        "env": {
          "IMMOWEB_HOME": "/srv/immoweb"
        }
      }
    }
  }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use IMMOWEB_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing IMMOWEB_HOME, or doctor will not find the local store left under the former root.

Automatic learning

This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a flag_alias candidate, and a teach on a query family without a playbook auto-synthesizes a playbook_candidate from the session's journal. Your job is judgment only: recall first, act on surfaced candidates, teach the final answer, playbook amend when you observe a correction. You never record failures by hand.

Step 1: recall before any discovery

Before list/search/drill commands on a new user question, pass the question as an argv or MCP tool argument to recall --agent. Do not interpolate user-controlled text into a shell command line.

Quoted recall "<question>" breaks on an apostrophe, which is ordinary English. A quoted heredoc breaks when a body line equals the delimiter, and that delimiter is published in these docs. Write the question with a non-shell file-writing tool, then read it back as data:

# Write the question verbatim with your file-writing tool (no shell involved).
# Command substitution on a file only ever yields data — the shell never
# parses the file's bytes as syntax.
QUERY=$(cat /path/to/question.txt)
immoweb-pp-cli recall "$QUERY" --agent

Prefer MCP: pass the question as the tool's query argument. "$QUERY" after a file read is argv-safe; putting the question itself in the command text is not.

The response envelope:

{
  "query": "...",
  "normalized": "<normalized form>",
  "query_entities": ["..."],
  "found": true | false,
  "match_score": 0.0,
  "results": [
    { "resource_id": "...", "resource_type": "...", "venue": "...",
      "confidence": 2, "entity_match": "exact|partial|unknown",
      "source": "taught|preseed|pattern", "warnings": ["..."] }
  ],
  "mismatches": [ /* only when --debug-mismatches */ ],
  "warnings": [ /* top-level */ ],
  "candidates": [
    { "id": 12, "class": "flag_alias | playbook_candidate",
      "summary": "...", "sightings": 3, "last_seen": "...",
      "rationale": "...",
      "next_action": ["<trial command>", "immoweb-pp-cli learnings confirm 12"] }
  ],
  "playbook": {
    "query_family": "...",
    "playbook": {
      "steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ],
      "entity_slots": ["$ENTITY"],
      "expected_tool_calls": 3
    },
    "slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } },
    "notes": "<workarounds + gotchas for this query family>"
  },
  "notes": "<duplicate surface for non-playbook callers>"
}

Empty-store short-circuit: if the store has no learnings, playbooks, or candidates yet (recall finds nothing and learnings list and learnings candidates are both empty), skip recall for the rest of this session instead of taxing every query; resume recall-first once something has been taught.

Step 2: decision tree

Read candidates, playbook, notes, results[0], and warnings in that order:

if Candidates present (warnings include "candidates_present"):
    -> candidates are try-then-confirm, never facts. Follow each candidate's
       two-step next_action verbatim: run the trial command first, then run
       `learnings confirm <id>` only after the trial verified the behavior.
       Reject a wrong candidate with `learnings reject <id>`.
    -> NEVER re-teach something recall surfaced as a candidate; confirm or
       reject that candidate instead of teaching a duplicate.
    -> candidates ride alongside playbooks and resource hits, not instead of
       them; continue with the branches below after acting on them.

if Playbook present:
    -> READ Playbook.notes verbatim FIRST (workarounds + gotchas the CLI surface doesn't expose)
    -> replay Playbook.steps in order, substituting Playbook.slots_resolved entries
       for the entity slot tokens. If a step's slot is unresolved, fall back to
       discovery for that step only.
    -> the Playbook's expected_tool_calls is a budget; if you find yourself running
       materially more, record the divergence via `immoweb-pp-cli playbook amend`
       at end-of-session.

elif Notes present (no Playbook):
    -> read Notes verbatim before any discovery step; they carry known gotchas
       for this query family even when no structured choreography exists yet.

elif Found AND Results[0].EntityMatch == "exact" AND Results[0].Confidence >= 2:
    -> skip discovery; fetch live data for Results[*].ResourceID in parallel

elif Found AND Results[0].EntityMatch == "partial":
    -> candidate hint, NOT a hit; read the resource title to validate before trusting

elif (any row in Mismatches[] when --debug-mismatches was passed):
    -> treat as cold start; the stored learning is for a different entity
       (different canonical resolved from query_entities)

else:  // Found == false, no playbook, no notes
    -> cold start; run discovery normally; teach the answer afterward (Step 4).
       If the family has no playbook yet, that teach auto-synthesizes a
       playbook candidate from this session's journal - you do not need to
       record one by hand.

Playbook and Notes are orthogonal to the per-resource path. A recall response can carry both a Playbook AND a Results[] hit - use both: the Playbook tells you which choreography to run; the resource hits short-circuit specific steps. Default to skipping mismatches; pass --debug-mismatches only when investigating cold-start surprises.

Candidate judgment details: learnings confirm <id> prints the candidate's full payload before materializing it - check that the printed payload matches the behavior you verified. learnings reject <id> tombstones the derivation signature so the same candidate does not resurface. The envelope carries only the few candidates worth acting on now; immoweb-pp-cli learnings candidates lists the full open set.

Graceful degradation: if learnings confirm is an unknown command, you are driving an older binary - ignore the candidates guidance and follow the rest of the protocol.
