Measured tools (21)

• search_resorts read-only

  Find ski resorts worldwide by name, country or distance. Returns at most 20 matches and does not expose the bulk resort index.

  Parameters:

  • near — object
  • limit — integer
  • query — string
  • country — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_conditions read-only

  Get current snow, reported lift and run counts, weather and season state. Lift and run counts are reported status, not guaranteed live.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_forecast read-only

  Get the available daily snow, temperature, freezing level and wind-hold risk forecast, up to 10 requested days.

  Parameters:

  • resort (required) — string
  • days — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• plan_my_day read-only

  Build modelled suggested runs in time order from forecast weather, sun, snow and mapped terrain. Only plans days inside the reported winter season; summer lift or bike-park operation does not count as open for skiing. Easy, intermediate and advanced exclude expert, freeride and extreme terrain; only expert permits it. Suggestions are not a connected route or live piste status.

  Parameters:

  • resort (required) — string
  • date — string
  • level — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• sun_on_the_mountain read-only

  Show modelled sun and shade windows for eight slope aspects, with local terrain-horizon shading where DEM coverage exists.

  Parameters:

  • resort (required) — string
  • date — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• route_on_mountain read-only

  Route between named pistes, lifts, the resort base or latitude,longitude coordinates using mapped OSM pistes and lifts. Names match accent-insensitively and partially (exact, then prefix, then contained words); a piste or lift split into several connected OSM pieces counts as one. A lift used as from resolves to its top station, where you ski away; a lift used as to resolves to its bottom station, unless coordinates say otherwise. Ambiguous names return candidates. Coordinates more than 5 km from the resort are rejected. Easy, intermediate and advanced avoid terrain above that level; only expert permits expert, freeride and extreme terrain.

  Parameters:

  • resort (required) — string
  • from (required) — string
  • to (required) — string
  • level — string
  • avoid_closed — boolean

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• avalanche_danger read-only

  Summarise the regional avalanche bulletin covering a resort: EAWS in Europe, avalanche.org centres in the US and Avalanche Canada, with zone, issuing centre, issue and expiry times and a link to the official forecast. Expired products are never shown as current. Never substitutes for the official bulletin or local advice.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• mountain_facts read-only

  Read mapped OSM terrain inventory, lift fleet, vertical, longest run, carefully matched Wikidata facts, season dates and modelled snow reliability.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• where_is_it_snowing read-only

  Rank the freshest recently reported snow from the cached EM Snow home-page ranking.

  Parameters:

  • limit — integer
  • hemisphere — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• best_time_to_go read-only

  Get historical snow odds from the local ERA5 archive and quiet-week guidance where the crowd scorer covers the resort.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• season_recap read-only

  Summarise the most recent completed ski season from the local ERA5 archive first.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• snow_reliability read-only

  Get an explainable snow-reliability score from long-run ERA5 snow depth.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• nearby_resorts read-only

  Find nearby resorts from the local EM Snow resort index.

  Parameters:

  • resort (required) — string
  • limit — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_webcams read-only

  Get nearby webcam images and their source links, with the required provider credit.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_snow_reports read-only

  Get recent visible community reports, including whether each came from the website or was relayed by an AI assistant.

  Parameters:

  • resort (required) — string
  • limit — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• watch_resort read-only

  Return a one-tap EM Snow URL where the person can watch a resort and optionally add dates. This tool does not collect email.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• add_snow_report

  Only relay a report from a person who is at, or was just at, the resort. Never invent a report. The report goes live immediately and is labelled as relayed via an AI assistant.

  Parameters:

  • resort (required) — string
  • text (required) — string
  • tags — array
  • rating — integer
  • observed_today — boolean

  Hints: read-only no · destructive no · idempotent no · open-world no

• suggest_resort

  Suggest a missing resort for human review. This never adds it directly to the resort index.

  Parameters:

  • name (required) — string
  • country (required) — string
  • lat (required) — number
  • lon (required) — number
  • notes — string
  • website — string

  Hints: read-only no · destructive no · idempotent no · open-world no

• get_extended_outlook read-only

  Get a 16-day daily outlook (snowfall, temperatures, freezing level, maximum gusts and, for the first days, precipitation probability) from EM Snow's self-hosted GFS and ECMWF IFS models. Days 1 to 7 overlap get_forecast; days 8 to 16 are low-confidence trend guidance only.

  Parameters:

  • resort (required) — string
  • days — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_resort_media read-only

  Get images for a resort that vision-capable assistants can show: nearby webcams with provider credit, a Wikimedia Commons photo with its per-file licence, author and source page, the EM Snow sun and shade teaser where one exists, and the resort page link. No trail-map image is available.

  Parameters:

  • resort (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• fly_this_mountain read-only

  Get a link that plays a simulated 3D tour of a resort in the EM Snow flyby (lifts up, named runs down, on the mapped piste network), or a tour of runs you name. Pick names match like route_on_mountain; ambiguous names return candidates with picker ids. Status is ready, limited (small mapped network, the tour may be short) or unavailable (too few named runs or no linking lifts; the resort page is returned instead).

  Parameters:

  • resort (required) — string
  • pick — array
  • runs — integer
  • level — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no
