  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 4

get_live_gauges

Today's official water-level readings (cm) at the cruise-critical gauges on the Rhine, Danube, Elbe and Seine, with each station's state and its percentile against thirty years.

Discovered
get_month_detail

Why a given month behaves the way it does on one of the four rivers: the seasonal hydrology, the thirty-year frequency, and the last five years' outcomes for that month.

Discovered
get_monthly_odds

Current 12-month cruise-disruption odds for one of Europe's main cruise rivers (chance a sailing day hits low water, or high water on the Seine). Refreshed daily from official sources.

Discovered
score_sailing

Score a specific river cruise: the chance a sailing departing on a given date meets low water (high water on the Seine) at its river's tightest stretch. Uses the live daily forecast where it reaches (~7 months) and the thirty-year weekly record beyond, plus what the same dates actually did in each of the last five years.
