What it can do

ToolWhat it says it does
compare_vitamin_d_yearCompare the vitamin D year of 2 to 5 places side by side in ONE call — 'Madrid vs Berlin vs Oslo, where do I actually get winter sun?'. Returns each place's months with sun, exact season span and viable days per year, plus rankedByViableDays. Use this instead of calling get_vitamin_d_year once per…
configure_sun_profileShow the user an interactive form for the four values every other tool assumes — Fitzpatrick skin type, fraction of skin exposed, age and target IU — with the minutes they need updating live. Use this when those values are unknown, when the user wants to change them, or instead of asking for them…
estimate_sun_sessionEstimate a sun session's outcome: 'I was (or will be) out N minutes — how much vitamin D did I make?' plus 'how long before I'd burn?' for the profile. Takes a start time (defaults to the day's best hour) and session minutes; returns estimated IU (with the physiological cap), average UV and…
get_current_statusWhether RIGHT NOW is a good moment for vitamin D synthesis at a location, using live Open-Meteo UV/cloud data when reachable (clear-sky model otherwise): current UV index, minutes needed now, and when today's window opens or closes.
get_my_citiesThe signed-in user's current city and favorite cities with coordinates and timezones, ready to feed into the public tools. Requires OAuth (scope profile:read).
get_my_historyThe signed-in user's sun history from the app's calendar: which recent days had viable sun, which they confirmed going outside, and their current streak. Covers the calendar days from `from` to `to`; records exist only for days the app was open, so a date missing from `records` means nothing was…
get_my_profileThe signed-in user's saved Vitamin D profile: skin type, exposed-skin default, age, target IU and their current city. Requires connecting with OAuth (scope profile:read). Call this FIRST for any personal question, then pass its values to the public tools instead of asking the user.
get_sun_forecastThe NEXT FEW DAYS of vitamin D sun at a location, using the live Open-Meteo forecast: per day the peak UV, average cloud cover, the synthesis window and the minutes needed, plus bestDay. Use this for any question spanning several days — 'which day this week should I go out', 'will it be better…
get_sun_timesSunrise, sunset, solar noon, civil dawn/dusk, morning AND evening golden hour, and day length (with day-over-day trend) for a location and date. Handles midnight sun and polar night. Pure sun times — for vitamin D questions use the vitamin_d tools instead.
get_vitamin_d_windowThe solar vitamin D synthesis window for ONE specific day at a location, for a personal profile: when UV is strong enough (index ≥ 3), the best hour, the clear-sky minutes needed to reach the target IU, and (with atTime) the minutes at the specific hour the user plans to go out. Returns…
get_vitamin_d_yearThe WHOLE YEAR of solar vitamin D for a location in a single call. monthsWithSun lists every month with at least one viable day (season edges count as partial months, see byMonth[].viableDays); solidMonths lists months where most days work; exactViableSpan gives the exact season boundaries…
log_sun_sessionSets a day's answer in the signed-in user's history calendar. Three values: confirmed=true (went out, the default), confirmed=false (had usable sun but stayed in), confirmed=null (clear the answer). Defaults to today. Requires OAuth (scope history:write).
search_cityFind a city in the app's database by name (any of the app's six languages works) and get its coordinates, IANA timezone and elevation — feed those into the other tools.
set_history_locationRecords where the signed-in user was over a range of past days, so their history stops assuming. Use it when the user corrects a stretch — get_my_history marks inherited days with `locationAssumed`, and the history calendar offers those stretches for correction. Pass a cityId from search_city, or…
update_my_profileSave the signed-in user's synthesis profile — skin type, exposed-skin fraction, age and target IU — to their account, so the app and every later call use them. Requires OAuth (scope profile:write). Only these four values are writable; favourites, cities and history are not.

In its maker's words

Know when the sun can make vitamin D where you are, for your skin type. Live UV data.
