SnowSure

Find resorts with the freshest powder snow right now. Returns resorts sorted by 24-hour snowfall. Use for "where is it snowing?" or "fresh powder" queries.

find_best_powder

Lodging near a resort via LUXSKI for the signed-in user. With a specific `hotelName` + checkIn + checkOut it PREBOOKS a live rate and returns a LUXSKI checkout URL to complete payment (we hold the rate + attribute the booking; we never charge). Without those it returns availability + a booking link. Requires a SnowSure user access token (OAuth). Payment always completes on LUXSKI.

book_lodging

Complete the trip: from a resort, find the nearest gateway airport(s) and get flight-search links from your home airport. The "get there" leg of the funnel — pair with find_best_powder / find_powder_trips (find fresh snow) → this → book_lodging (stay). Args: resort (slug, required — use search_resorts to resolve a name), optional origin (your home-airport IATA like DEN, or a city name).

find_flights_to_powder

Get the global snow report with top-ranked resorts by snow conditions. Returns resorts sorted by SnowSure score, forecast, or recent snowfall. Use this for "where has the best snow?" or "top ski resorts right now" queries.

get_snow_report

Will the lifts run? A 48-hour operating-risk estimate from the Open-Meteo forecast — wind-hold (gusts), visibility, cold (wind-chill), and heavy-snow control delays. Modeled guidance, NOT the resort's own operating decision — always check live lift status.

get_operating_risk

List the signed-in user's alert subscriptions. Requires a SnowSure user access token (OAuth).

list_alerts

List SnowSure insight categories (live conditions, current season, last season, forecast trust, patterns, SnowSure index, ground truth). Use before get_insights to choose a category filter. Lighter than raw leaderboards — retrospective and verification-backed cards.

list_insight_categories

List the signed-in user's saved resorts. Requires a SnowSure user access token (OAuth); without one it returns an authorization-required error telling the agent how to connect.

list_saved_resorts

Single-resort data with a REQUIRED card parameter that picks the interactive UI. card=guide → resort info card (elevation, lifts, season dates). card=photos → photo gallery carousel. card=snow → snow conditions card (score, base depth, forecast). card=full → detailed markdown only, no card. "Resort guide" → card=guide. "Photos/gallery" → card=photos. "Conditions/forecast" / "is it open right now, base depth, lifts open of total" → card=snow (open status, base depth, and lifts open of total). Prefer get_resort_info / get_resort_photos when available (same cards).

get_resort

Fetch SnowSure-unique ML/AI trend datasets from the public REST API. Use for powder-day leaders, bluebird-day leaders, bluebird predictions, improving/stable/declining score pulse, per-model accuracy weights, daily SnowSure score component history, ML extended outlook (days 8–14), global forecast trust, and powder/bluebird event logs. Start with dataset=catalog. Its leaderboards read CURRENT-season counters and are global — they take no season and no country/state filter. For a past season, or for any ranking scoped to a state, province, country or region ("most snow days in Maine last season", "rank BC resorts by season snowfall"), use get_season_leaderboard instead. Prefer get_insights for narrative intelligence cards; use this for raw rankings and time series.

get_ml_trends

Personalized snow report for the signed-in user's saved resorts — live conditions for each, ranked best-first (open resorts with the freshest snow on top). Requires a SnowSure user access token (OAuth).

get_my_snow_report

Plan a multi-stop ski road trip: picks the top-scoring resorts in a region, orders them into a drivable route (nearest-neighbour, minimal backtracking), allocates your days across stops, estimates each driving leg, and folds in live conditions plus chain-control where covered. Args: region (required), days, optional pass.

plan_ski_road_trip

Get ski trip recommendations based on dates, preferences, and conditions. Suggests best resorts for a given time period.

plan_ski_trip

Powder Reels — SnowSure archived storm timelapses with verified accumulation data burned into the frames ("Proof of Powder"). Use for "how much did it snow at X last night", "show me the storm at Alta", "biggest powder days this season", or any request for storm footage / timelapse / receipts. Returns reels newest-first with watch links.

get_powder_reels

Get a summary of snow conditions across an entire region or country with statistics and top resorts.

get_regional_summary

Remove a resort from the signed-in user's saved list. Requires a SnowSure user access token (OAuth).

remove_saved_resort

INTERACTIVE RESORT GUIDE CARD (Resort Info sidebar UI) — elevation, vertical, lifts, runs, skiable acres, average snowfall, season dates, ski passes, editorial description, hero/gallery carousel. REQUIRED when the user asks for: resort guide, mountain profile, resort info, lifts/runs/vertical/skiable area, season dates, ski passes, or "tell me about the mountain" (non-weather). Answers single-resort stat questions: base/summit elevation, vertical drop, skiable area, average annual snowfall. Examples: "Aspen Mountain resort guide", "how many lifts at Jackson Hole", "what is the base elevation at Arapahoe Basin". For X-vs-Y stat questions use compare_resorts. Do NOT use get_resort (that shows the snow conditions card).

get_resort_info

INTERACTIVE PHOTO GALLERY CAROUSEL — official SnowSure resort photos (hero + Sanity gallery). REQUIRED for: photos, pictures, images, gallery, "show me photos of Vail/Aspen". Never use web search or inline images — call this tool. Do NOT use get_destination, get_resort_info, or ask_snowdata for photo requests.

get_resort_photos

One resort's own snowfall history: season totals, comparison to its 5-year and 30-year averages, and best months to visit. Scoped to a SINGLE resort — for "which resort in <state/country/region> led <metric> last season", use get_season_leaderboard instead.

get_snow_history

Get detailed day-by-day weather forecast for a resort including temperature, snowfall, wind, and conditions for each of the next 7 days — 14 with SnowSure Pro, or for a favourite resort when signed in.

get_weather_forecast

Get live webcam links and status for a resort to see current on-mountain conditions visually — answers "show me the webcam / live cam at <resort>", "current conditions on camera", and named-cam lookups.

get_webcam_status

List the resorts on a ski pass, optionally filtered to a region — answers "is <resort> on the Ikon Pass" and "what resorts does the Epic Pass include". Returns names + SnowSure slugs you can pass to get_resort.

find_pass_resorts

Driving access for a resort — answers "do I need chains to get to <resort>" and "is the road to <resort> open": a SnowSure drive call, feeder-city Saturday drive times on the PGRI pilot, plus chain-control / mountain-pass / road-surface conditions on nearby highways (California via Caltrans, Washington via WSDOT, Oregon via ODOT TripCheck, Montana via MDT 511, Wyoming via WYDOT 511, Colorado via CDOT, Utah via UDOT, British Columbia via DriveBC, Ontario via Ontario 511, New England via Compass C2C, Virginia via VDOT 511, New Zealand via NZTA). Returns 'no road data' outside the covered area. Links to the official DOT map; the resort's road status is authoritative.

get_road_access

Live roadside DOT/CCTV camera stills on the highways near a resort — shows what the drive actually looks like right now (California via Caltrans, Washington via WSDOT, Mount Rainier NP via NPS, Oregon via ODOT TripCheck, Montana via MDT 511, Wyoming via WYDOT 511, Utah via UDOT, British Columbia via DriveBC, Maryland via CHART/iMAP, New England via Compass C2C, Virginia via VDOT 511, New Zealand via NZTA, Alpine Europe via NAPSPAN). Distinct from resort webcams. Returns 'no road cameras' outside the covered area; each camera includes a live image URL.

get_road_cameras

Measured roadside weather (RWIS) on the highways near a resort — surface + air temperature, visibility, wind, precipitation (Colorado via CDOT, Washington via WSDOT, Oregon via ODOT TripCheck RWIS, Montana via MDT 511, Wyoming via WYDOT 511, Utah via UDOT, New England via Compass C2C). Sensor data on the actual road, distinct from the modeled get_operating_risk. Returns 'no road weather' outside the covered area.

get_road_weather

Save a resort to the signed-in user's favorites. Requires a SnowSure user access token (OAuth). The slug must be a real SnowSure resort.

save_resort

Search for ski resorts by name, country, or region. Returns matching resorts with basic conditions. Use for "find resorts in [location]" or "search [name]" queries.

search_resorts

Rank resorts by how a season actually went, scoped to a place. This is the tool for "which <place> resort had the most <metric> last season" — the single most common retrospective question agents ask. Scope by state or province (Maine, Montana, Wyoming, British Columbia, Hokkaido, Nagano, Valais, Tyrol), by country (Switzerland, Japan, Canada), or by region (north-america, europe, asia, oceania, south-america, or a colloquial range: alps, andes, rockies, scandinavia). Metrics: snow_days, total_cm, powder_days, bluebird_days, max_storm (biggest single 24h snowfall, with the date it fell), peak_depth, longest_dry_spell. Covers 30 seasons back to 1996, so it answers historical and multi-season questions too, not just last season. Season accepts 2025, "2025-26", 2026, or "last" and resolves them all to the same season. Backed by ERA5 reanalysis across the full season window, so figures cover the entire season rather than only the days SnowSure has been live. Use get_snow_history for ONE resort's own history, get_monthly_snow for typical month-by-month climatology, and get_snow_report or find_best_powder for conditions RIGHT NOW.

get_season_leaderboard

Resorts whose season OPENING DATE is a specific day — answers "what opens today?", "opening this week", or "which resorts start their season on June 27?". Returns only resorts scheduled or confirmed to open on that date, NOT all currently-open resorts. Prefer over get_southern_hemisphere_report for opening-day questions. This tool is date-scoped, so it is the wrong shape for two neighbouring questions: for a RANKED retrospective ("which resorts opened earliest for the 2025-26 season, top 6 by verified opening date"), use get_insights with category=season_calendar; for historical norms ("which resort typically opens earliest each season", "is X usually open by Thanksgiving"), use ask_snowdata.

get_season_openings

Details for a multi-resort ski pass (Epic, Ikon, Mountain Collective, …): operator, season pricing tiers, destination count, regions, and the buy link.

get_pass

Get categorized SnowSure intelligence insights (not just snow totals). The last_season category is the one to reach for on retrospective questions — how a finished season compared to its 5yr norm, who led it, where the models were trustworthy. Also covers model accuracy by region, longest dry spell, and trend pulse. Insights are hemisphere-scoped narrative cards; when the question names a specific state, province, country or region and wants a ranked list, use get_season_leaderboard instead. Filter by category or insightType=intelligence to skip simple leaderboards.

get_insights

Get snow conditions for Southern Hemisphere ski resorts (Australia, New Zealand, Argentina, Chile) currently in season. Answers "is Perisher / Portillo / Valle Nevado open right now and what are the current conditions", "is the Australian ski season underway", and "which Southern Hemisphere region — the Andes, Australia, or NZ — has the best snow right now". Use for June–October SH ski queries. Prefers operator-verified data when available. Do NOT use for a specific opening DATE — use get_season_openings instead. Note that the SH is not the only place to ski in the northern summer: a handful of NH glaciers run summer or year-round operations (Zermatt/Matterhorn Ski Paradise skis all year; Passo dello Stelvio, Stryn and Galdhøpiggen run deep into autumn; Hintertux, Saas-Fee, Tignes, Les Deux Alpes and Timberline have dated summer windows that close). For those, call get_resort on the named glacier — summer windows are tracked per resort and a glacier being famous for summer skiing does not mean it is open today.

get_southern_hemisphere_report

Storm Watch: named multi-day storm systems the models are flagging days ahead, grouped as one event across every resort in the path and ranked biggest first. Use for "is a storm coming", "what's the next big system", "where will it dump this week". Each event carries its window, the forecast total per resort, and a confidence tier (watching / likely / locked). FORECAST, NOT OBSERVATION — nothing here has fallen yet; use get_snow_report or find_best_powder for snow that already has. Returns no events when nothing is being watched, which is the normal state outside a storm cycle.

get_storm_watch

Subscribe the signed-in user to snow alerts. Requires a SnowSure user access token (OAuth). type: 'powder' (OBSERVED fresh snow >= thresholdCm in 24h), 'forecast' (the 14-day FORECAST clears thresholdCm within windowDays — the proactive 'tell me when a powder trip is forming' watcher), 'opening' (resort opens for the season), or 'bluebird' (powder day then clear skies).

subscribe_alerts

Historical odds for a SPECIFIC trip window at one resort — 'Whistler on March 27', 'Vail Jan 10–17'. From ~30 years of ERA5 monthly history it blends the window's months (weighted by days) into: the snow-day probability (the headline — for a short window how OFTEN it snows beats how MUCH falls in a season), window-scaled expected snowfall and typical base depth, the same window across the last 5 individual seasons, and the best nearby month (±1) by snow-day odds. Window max 31 days; dates are YYYY-MM-DD. This is HISTORY, not a forecast and not a prediction — for the next 14 days use get_weather_forecast, and for a whole-month question use get_monthly_snow. Windows with under 5 tracked seasons return insufficient rather than thin odds.

get_trip_window

Typical snow for a resort MONTH BY MONTH, from ~30 years of ERA5 reanalysis — average snowfall, snow days, base and peak depth, and biggest storm, plus per-season totals. Use for date-choosing questions: 'what is February usually like at Vail', 'when should I go', 'is January or March better'. This is HISTORY, not a forecast and not a prediction — for the next 14 days use get_weather_forecast, and for right now use get_resort. Months with too little history are withheld rather than shown thin; every month returned carries yearsTracked so you can cite the evidence.

get_monthly_snow

Remove one of the signed-in user's alert subscriptions by id (from list_alerts). Requires a SnowSure user access token (OAuth).
