Booking.com — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the booking-com-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 booking-com --cli-only
   

2. Verify: booking-com-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 1.26.3 or newer):

go install github.com/mvanhorn/printing-press-library/library/travel/booking-com/cmd/booking-com-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.

When to Use This CLI

Use this CLI when an agent needs to search Booking.com, drill into hotel detail, compare candidates, or work with a user's logged-in Booking account (trips, wishlist, Genius rewards). It is the right choice for cheapest-date sweeps, price-drop tracking, and multi-leg itinerary planning — work that compounds across calls and benefits from local SQLite history. Reach for it instead of generic web-scraping tools because it owns Booking's AWS WAF clearance via Surf+Chrome TLS, the CSRF/cookie composition for /dml/graphql, and the Chrome cookie import for authenticated surfaces.

Unique Capabilities

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

Local state that compounds

• prices cheapest — Sweep candidate checkin dates for a fixed-night stay at one hotel and return the lowest nightly totals from local price_history.

  Reach for this before recommending dates to a user. It removes Booking's manual click-through-every-date dance and exposes the seasonal price floor for the property in one call.

  booking-com-pp-cli prices cheapest --slug auliviaopera --country fr --window 2026-06-01..2026-08-31 --nights 3 --agent
  

• prices cheapest-destination — Sweep candidate checkins across a destination's top results and return the cheapest (property, date) pairs under a max-price ceiling.

  Use when an agent has a flexible-date traveler in a flexible-property mood. Returns a budget-constrained Pareto frontier instead of one ranked list per date.

  booking-com-pp-cli prices cheapest-destination --query Paris --window 2026-06-01..2026-08-31 --nights 3 --max-price 250 --agent
  

• watch run — Track a set of (hotel, checkin, checkout) tuples and surface only the ones whose latest price dropped a configurable percentage below their trailing median.

  Schedule this nightly. Returns empty most days, returns gold when a watched property dropped enough to act on.

  booking-com-pp-cli watch run --min-pct 7 --agent
  

• destinations price-band — Aggregates price_history for a destination's synced properties and emits per-month median, min, and max nightly rate plus contributing property-count.

  Use when planning a flexible-month trip. Returns the cheapest month + 'avoid this month' signal without manual searching.

  booking-com-pp-cli destinations price-band --query Paris --year 2026 --nights 3 --agent
  

• search — After sync populates the local property store, FTS5 ranks free-text queries over name + description + amenity strings with BM25, no network call.

  After repeated sync calls have built a corpus, this lets an agent answer cross-destination property questions without re-hitting the network.

  booking-com-pp-cli search "boutique near louvre with rooftop" --agent
  

Agent-native plumbing

• wishlist drops — Joins the authenticated wishlist with the local price_history and surfaces saved properties whose latest observed price is N% below the previous observation.

  Use Sunday morning. Returns the small set of wishlist items worth booking now, instead of forcing the user to eyeball 30-40 saved properties.

  booking-com-pp-cli wishlist drops --since 168h --min-pct 5 --agent
  

• compare — Fetches detail + reviews for two hotels in parallel and emits a paired struct (price, score, amenity Δ, distance, free-cancellation, breakfast, recent-review counts).

  When an agent has narrowed to two finalists, reach for this instead of re-rendering both detail pages and asking the user to read both.

  booking-com-pp-cli compare auliviaopera plazaathenee --checkin 2026-07-15 --checkout 2026-07-18 --agent
  

• trips deadlines — Walks authenticated upcoming trips, extracts the free-cancellation-until deadline from each trip detail, and returns trips whose deadline is within a configurable window.

  Booking penalizes missed cancellation deadlines. Run this each Monday morning to catch deadlines before they expire.

  booking-com-pp-cli trips deadlines --within 168h --agent
  

• trips export — Walks authenticated past-trip list, opens each trip detail, and emits a deterministic CSV (confirmation, property, checkin, checkout, currency, total, address) ready to paste into expense systems.

  Use Monday morning for last week's reimbursements. One call replaces clicking through every past trip.

  booking-com-pp-cli trips export --state past --since 2026-01-01 --format csv
  

• reviews stats — Local SQL group-by over synced reviews; counts and median score per score-band, language, and traveler-type bucket. Mechanical, no NLP.

  Reach for this when an agent is matching property fit to a traveler type. Returns a bucket distribution instead of forcing the agent to read 1000 reviews.

  booking-com-pp-cli reviews stats --slug auliviaopera --country fr --by score-band,language,traveler-type --agent
  

Reachability mitigation

• trip plan — Given multiple destination + date legs and a total budget, picks the cheapest property per leg whose summed nightly totals fit the budget, with a bounded combinatorial fallback when greedy busts.

  For multi-city European itineraries the agent can answer the budget-constrained question in one round-trip instead of asking the user to iterate per leg.

  booking-com-pp-cli trip plan --leg Rome:2026-07-10:2026-07-13 --leg Florence:2026-07-13:2026-07-16 --leg Venice:2026-07-16:2026-07-20 --budget 1800 --filters free_cancellation,breakfast,score>=8 --agent
  

• genius impact — Runs an absorbed search twice — once with the authenticated cookie (Genius rates applied) and once anonymously — and diffs price-per-property to surface the Genius savings delta.

  Use when an agent helps a user evaluate whether a Booking Genius tier is worth chasing. Reports the actual unlocked discount on a real search.

  booking-com-pp-cli genius impact --query Paris --checkin 2026-07-15 --checkout 2026-07-18 --adults 2 --agent
  

• deals mobile-rates — Re-runs an absorbed search with a Chrome mobile UA on top of the desktop call and diffs to surface mobile-only discounts Booking hides from desktop users.

  When an agent is hunting savings, reach for this before recommending the desktop-quoted rate. Mobile rates can be 5-15 percent lower on the same hotel + dates.

  booking-com-pp-cli deals mobile-rates --query Paris --checkin 2026-07-15 --checkout 2026-07-18 --agent
  

HTTP Transport

This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls.

Discovery Signals

This CLI was generated with browser-observed traffic context.

• Capture coverage: 1 API entries from 14 total network entries
• Protocols: ssr_html (95% confidence), rest_graphql (70% confidence)
• Auth signals: none; cookie — cookies: aws-waf-token, bkng, bkng_sso_session, cgumid, bkng_prue
• Generation hints: requires_browser_http, requires_browser_cookie_for_auth_endpoints, has_ssr_html_primary_surface, has_csrf_token_for_graphql, supports_offset_pagination
• Candidate command ideas: search — SSR /searchresults.html returns 25 property cards parseable from HTML.; hotel get — SSR /hotel/<country>/<slug>.html returns full hotel JSON-LD.; reviews list — /reviewlist.html exists as a separate paginated surface.; destinations autocomplete — Autocomplete dropdown on homepage fires destination resolver.; trips list — secure.booking.com/mytrips.html loaded with cookie auth and rendered user-specific UI.; wishlist get — www.booking.com/mywishlist.html?wl_id=<id> loaded with cookie auth.; rewards get — secure.booking.com/rewards_and_wallet.html linked from authenticated header.; profile get — secure.booking.com/mysettings.html linked from authenticated header (showed 'Matt Van Horn, Genius Level 3').
• Caveats: ssr_dominant: All observed user-visible pages are server-rendered. Initial searches, hotel detail, trips, and wishlist deliver their data in HTML rather than XHR/GraphQL. The /dml/graphql endpoint exists but was not exercised during this capture; it is documented for future map-markers and review-pagination work.; empty_authenticated_state: User's trips and wishlist were empty during capture, so response shape for populated cards was not directly observed. Schema fields are inferred from Booking.com documentation, community wrappers, and the empty-state markup.

Freshness Contract

This printed CLI owns bounded freshness only for registered store-backed read command paths. In --data-source auto mode, those paths check sync_state and may run a bounded refresh before reading local data. --data-source local never refreshes. --data-source live reads the API and does not mutate the local store. Set BOOKING_COM_NO_AUTO_REFRESH=1 to skip the freshness hook without changing source selection.

Covered paths:

• booking-com-pp-cli cars
• booking-com-pp-cli trips
• booking-com-pp-cli wishlist

When JSON output uses the generated provenance envelope, freshness metadata appears at meta.freshness. Treat it as current-cache freshness for the covered command path, not a guarantee of complete historical backfill or API-specific enrichment.

Finding the right command

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

booking-com-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.

Recipes

Cheapest week in Paris this summer

booking-com-pp-cli prices cheapest-destination --query Paris --window 2026-06-01..2026-08-31 --nights 7 --max-price 200 --agent --select '[].property_name,[].checkin,[].price'

Sweep every 7-night window in summer and return the cheapest property-and-date pairs under $200/night, with --select narrowing the response to the three fields an agent needs.

Wishlist drop digest for Sunday morning

booking-com-pp-cli wishlist drops --since 168h --min-pct 5 --agent

Walks the user's wishlist and returns only items whose latest price is at least 5 percent below the previous observation in the last week.

Compare two hotels with detailed deltas

booking-com-pp-cli compare auliviaopera plazaathenee --checkin 2026-07-15 --checkout 2026-07-18 --agent

Side-by-side amenities, price, score, distance, free-cancellation, and recent-review counts for two slug-identified properties.

Free-cancellation alarm for the week ahead

booking-com-pp-cli trips deadlines --within 168h --agent

Walks authenticated upcoming trips and surfaces those with a free-cancellation deadline in the next week, sorted by urgency.

Plan a 3-city Italian itinerary against a budget

booking-com-pp-cli trip plan --leg Rome:2026-07-10:2026-07-13 --leg Florence:2026-07-13:2026-07-16 --leg Venice:2026-07-16:2026-07-20 --budget 1800 --filters free_cancellation,breakfast,score>=8 --agent

Searches each leg in parallel and picks the cheapest property combination per leg whose summed nightly totals fit the budget.

Auth Setup

Public search, hotel detail, reviews, destinations, and map markers run anonymously through Surf with a Chrome TLS fingerprint that clears Booking.com's AWS WAF challenge without a clearance cookie. Authenticated commands (trips, wishlist, rewards, profile) need a logged-in Chrome session: run booking-com-pp-cli auth login --chrome once and the CLI imports the booking.com session cookies so subsequent authenticated calls replay through Surf.

Run booking-com-pp-cli doctor to verify setup.

Agent Mode

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

• 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:

  booking-com-pp-cli account --agent --select id,name,status
  

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

• Offline-friendly — sync/search commands can use the local SQLite store when available

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

• Explicit retries — use --idempotent only when an already-existing create should count as success

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. 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.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

booking-com-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
booking-com-pp-cli feedback --stdin < notes.txt
booking-com-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.booking-com-pp-cli/feedback.jsonl. They are never POSTed unless BOOKING_COM_FEEDBACK_ENDPOINT is set AND either --send is passed or BOOKING_COM_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

booking-com-pp-cli profile save briefing --json
booking-com-pp-cli --profile briefing account
booking-com-pp-cli profile list --json
booking-com-pp-cli profile show briefing
booking-com-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
